All men have a biological sexual need for men. And this need is much more constant, deeper and intense than their sexual need for women, which is periodic at best, and is not so universal as the former. Also, under natural circumstances, sexuality for women doesn't lend itself into any kind of emotional or social bonding if you're a masculine gendered male (the real meaning of straight). Only feminine gendered males (the real meaning of gay) have a heterosexual orientation.
Since our societies have developed strong, often invisible social systems for heterosexualizing males from the start, most males learn to develop their sexuality for women, which is secondary in nature, into their primary sexuality by suppressing and blocking their sexual need for men, which is primary in nature. However, a considerable percentage of males don't have enough sexuality for women to facilitate this process. Does it mean they're gay? No.
If all of these males decided to be 'gay' then there would be a sizable section of society which is 'gay' -- and 'gay' would not mean 'queer' anymore. Most of them prefer to suppress or hide their sexuality or fuffill it quietly and remain as 'straight' by pretending to like women and even getting married and stuff, just in order to be 'straight' because that is what they are, since they're masculine gendered.
Some males choose to be 'gay' while others prefer to hide their sexuality? Why is that? Are the ones hiding their sexuality incapable of accepting their own sexuality? Yes. Is it their fault? Although, the gays are fond of saying this, the answer is "No". They are no different than the rest of the straight males who suppress or hide their sexuality for men too. It's the Western society and the 'homosexuals' in particular, who are to be blamed for this situation.
The so-called "homosexuals" claim that there is no difference between them and those who hide their sexuality. But this is not true at all. Then what is the difference between those who choose to be 'homosexuals' and those who shun away from it? The difference is one of gender -- of masculine and feminine gender.
Gender refers to the inner sense of being a male or a female, inspite of one's male outer sex. The Western society doesn't acknowledge Gender as a valid human trait (they claim there's nothing to it but just social roles), and neither does Western science. However, it exists in nature, and it plays an extremely important role in the lives of men, and their social identities.
So, although, the Western society will not conduct any study on it, the distinction between those who hide their sexuality for men and reject the gay identity and those who accept the gay identity is basically that of being masculine or feminine. The Gay or homosexual identity is basically built for the effeminate male -- in fact, whether or not he likes men. That is why the transgendered heterosexuals align with the homosexuals as LGBT, rather than share their identity with the straights. The origins of the concept of homosexuality (by a person of the third sex called "karl Ulrichs") also makes this fact perfectly clear. karl Ulrichs used the term for the third sex, that he referred to as half-males/ half-females. He called them "men who like men," or "homosexuals," because he was greatly mistaken about what the sexuality of 'straight men' (whom he mistook for being constantly and exclusively into women, because that is what he saw) was. In fact, Karl was not a 'man' (s)he was an 'inbetween' him/herself. In fact, the term 'homosexuality' is so corrupted by the third genders, that it can no longer be used to denote (straight) men's sexual attraction for/ relationships with men, without harming the freedom of men to choose this trait with dignity and a valid representation of themselves (something the Western society is already intent on doing -- and that is what the conspiracy against men is).
That is why the effeminate males who like men, from early on in their life, realise they're different from the rest. Even before they develop sexual feelings. And this difference is seen for what it is. As being a girl inside a boy. Only later do sexual feelings develop, and while the regular boys learn to hide their sexual feelings for men, as they start seeing it as abnormal (that is what the society wants them to view male eroticism as), the effeminate guy sees this as his 'Gender' role as a 'different' boy, (since, he sees himself as a girl, and liking men is propagated as a 'girl's' thing, this fits in perfectly well with his inner girl, and he starts to see this combination as natural) and (s)he gets the psychological/ moral base for developing this sexuality, as others struggle to kill it. Indeed, the feminine gender of the 'different' boy is so entwined with his/her sexual desires for men and because of the social conspiracy which gives the two a combined social category (homosexual), the feminine gender of the 'different' boy grows into a separate sexual identity. By the time (s)he grows up, (s)he is all ready to transcend into the gay world, the gay identity, and fits in there like a duck takes to water.
However, all the regular boys fight with their sexuality for men, because it is sold to them as being 'unmanly,' a girl's thing (and boys do want to grow up into men, not into queers), they kill off most of their sexuality for men while in its bud, but it doesn't totally go away. They hide and camouflage the rest and give it vent through ways that doesn't make them 'gay' as per the arbitrary roles set by the Western anti-man forces (led by the media). All this takes a lot of toll on the boys and they deal with this by constantly and obsessively making fun of the 'gays' (the effeminate ones who do get the social space to celebrate their sexuality for men) and by having sexual play between themselves which is meant to be just as silly, boyish pranks, not letting them become serious enough to interfere with a 'heterosexual' identity. And they go on to work on their attraction for girls, using artificial means, and grow it into a full-fledged heterosexual identity. Straight (regular) boys atchieve this heterosexuality in different measures, the rest is all exaggerated and pretended to fit into the social image that they are required to have as a 'heterosexual male.'
In all of this, the straight boys with no sexuality for women are completely left out. They can't relate with the 'gay' model, because, like the effeminate boy, they don't fit into the 'different' phenomenon, since they are not feminine gendered, and even though the definition of 'homosexuality' doesn't talk about the femininity part, and its hidden, they sub-consciously react to it. But, they also don't have any sexuality for women to work on to fit perfectly into where they belong -- with the other straights. So, they learn to fit into this strange situation, by making a lot of personal sacrifices (they may develop a hatred for sexuality for men, or may learn to submit to it quietly or both) and adopting several faces.
The straight boys with exclusive sexuality for men cannot naturally pass over to the 'homosexual' identity, even if they use it quietly for sex, especially as they get older, since the Western straight space is closed to sex between men. However, the Western system of sexual orientation also forces and misleads many of these straight boys/ men to be in this confusing situation, where they start to see themselves as 'gay' (since 'gay' is formally defined as "men who like men"), but never really relating with the real 'gays' or with the gay community or the gay scene. These few straight guys may take on the gay identity too, but without ever relating with the other gays, and spending most of their time with the 'straights' and not with the gays. In fact, many of them have quietly sex with the other straight males, within straight spaces. However, this is never acknowledged even between the two straight guys in a sexual or even emotional relationship with each other, and so, the Western society which wants to showcase 'straight' males as heterosexual can continue with its biggest fraud. These relationships between two straight males, in the straight space, is almost always where one of them has a well developed sexuality for women, while the other is exclusively into men. The straight guys too consider the straight guy with an exclusive sexuality for men as one of them (and not one of the gays), and usually try to keep quiet about his 'sexuality' or downplay it, even when they're aware of it. On the contrary, the gay world sees this straight guy as 'straight-acting' or as someone who is not being himself but is acting like someone he is not, when nothing is farther from the truth. Gays are expected by gays themselves to be feminine, and why not.
The young straight guy with exclusive sexuality for men has an extremely traumatizing time dealing with his sexuality, primarily because, the western politics of male gender and sexuality, with its 'sexual orientation' system, literally forces him to choose between his sexuality for men, which is socially invested solely with the half-male/ half-female identity (called "homosexuals") and his 'gender orientation' which is strongly with the rest of the straight guys. In fact, if it is not for the aritificial social engineering by the Western society and its science, the sexuality of such straight guys for men match perfectly with the sexuality of the rest of the straight guys -- since they all actually have a strong sexuality for men. The only difference is that the former do not like women, which should not make a difference amongst men, because heterosexual relationshps should properly be formed outside of men's spaces, not within it. The gap exists and assumes such importance only because the latter's sexuality can adjust with the society and the former's sexuality doesn't. And it makes the latter feel socially 'superior' or at least in a more comfortable situation. Whatever difference exists is social and aritificial.
And the transgression for the young straight guy with exclusive sexuality for men, from 'straight' to 'gay' (if they choose to do it) is never as smooth as that of the feminine guys, but always traumatic. They have to kill a huge part of who they are to be able to express their sexuality, and take on an identity with people he has nothing in common with, except that they are both open about their sexual need for men, while the rest of the straight guys are not.
In fact, the sexuality of the straight guy with an exclusive interest in men is totally different from the sexuality of a 'gay' guy for men. A 'gay' basically relates with a man sexually, imagining himself to be a woman (in different degrees). For a gay being sexual with a male is to give expression to his feminine gender, and it enhances his sense of being a female. He desires a man being a 'female'. So, gays often call each other with girls names and impersonify girls in their behaviour. While the straight guy who acknowledges his sexuality for men, likes other men being a man. Aligning with another male sexually is an expression of his manhood, his masculinity and it enhances his sense of being a man. He desires another man being a man. The Western system of sexual orientation which sees both gays and straight guys with open sexuality for men as one category, is based on the special hostile and misleading situation created by Christianity which didin't care about the gender differences of males, and only wanted to classify 'sodomy' as a separate category of sin. The concept of 'homosexuality' which is a great mismatch of different genders of males, has evolved out of this need to isolate and punish sodomy, rather than to facilitate a just and valid system of human classification.
In fact, gays often reject the idea of the gay space actually being a 'third gender', feminine gendered space by claiming that many 'gays' or 'homosexuals' are 'masculine'. They are referring to these very straight guys with an open sexuality for men, who have no place in the society, and some of them as mavericks come and takek up the 'gay' identity, but never really mixing with the actual 'gays' or relating with them.
Just because things happen in the Western world doesn't mean they're right or valid.
