The "gay" population is definently increasing each year, and it's in part to our culture, it's definition of "gay", and from the exposure of homosexuality period.
ING - Actually it has held a steady percentage of the population up to current.
We appear to have more because people are no longer hiding in the closet.
- Though - the next one could show a rise - as data shows a rise in homosexual births when populations are under stress, - and the world is very OBVIOUSLY under stress right now. This is possibly to lower future births, - so we have enough resources, food, etc., until we get back to normal.
Most all porn sites offer "gay" porn now, so any male who just has an edge to see the act or is curious can and shall witness it through porn which is 90% of the time, deceiving. It also doesn't help that the media and our culture has a definitive answer for those who even have an "edge" or curiosity about simply an homosexual act.
I've met quite a few bisexual men in my life, and though the men I've met were young, roughly my age at 22, whenever I asked them why they prefer both men and women, I always got the same responses. Either they prefer to sexually engage with a male, but mentally prefer a relationship with a female, that they like sexually pleasing in general be it a male or female, or they are still figuring out what they like but often fear they always may like both and therefore face the a battle between them both for eternity, especially if they consider getting married which would suggest they are stuck with that gender.
ING - I've posted info on this subject in the past. Several big studies showed that most women are actually bi, and so are a lot of men. Our society trains us to hate such, so we follow the so-called "norm!"
These studies used only male or female pheromones, releasing them into rooms with either a male or female, and registered the reaction in the "sex" areas of the brain. True heterosexual's brains only reacted sexually to the opposite sex. True homosexual's brains only reacted to same sex pheromones. BUT - the majority of the brains reacted to both meaning bi, - and follow-up studies using normal materials such as images, porn, etc., backed up the results.
Ones Sexual role has a huge play in the life of a gay male, actually with lesbian women too. Typically, it's not common to find a masculine gay male who prefers a 'top' role, to which the masculinity is often sought after. Usually gay males with authoritative jobs tend to be more submissive too, ironic really, and though there's always exceptions, it's not common. Whether the submissive role is a learned behavior, or an acquired one, men typically associate that role to that of a female which often leads a male on the path of the modern day homosexual.
ING - Actually it has been shown that even heterosexual men, at the top of the food chain, in sado-masochistic play, will often choose the submissive role. It is interesting.
I once was best friends with a lesbian, not a bi curious one, which I find most 'lesbians' are, or atleast who claim to be lesbian, and she was more of a dominating figure who preferred the top role. She was the first female I had ever developed feelings for, and given the opportunity, I would of been willing to have sex with her. After analyizing it I figured it was because of a few different factors, one of then obviously being more dominant physically. Not just sexually either, but the walk, talk, etc. Second, we clicked xP and though she was beautiful, I wasn't sexually attracted to her, but rather who she was as a human being. The whole thing for me was a reality check on preference and how sexual roles, society, etc play apart into ones sexual identifier be it homo or heterosexual. It leads me to believe that we're not Gay at birth, it's a combination of many things.
