"From an evolutionary perspective we tend to think of sexual behavior as a means to an end for reproduction," Diana Fleischman, an evolutionary psychologist at the university and study author, told University of Portsmouth News. "However, because sexual behavior is intimate and pleasurable, it is also used in many species, including non-human primates, to help form and maintain social bonds. We can all see this in romantic couples who bond by engaging in sexual behavior even when reproduction is not possible." The results of our study are compelling because using two very different methods; they arrived at the same conclusion," Fleischman said, according to University of Portsmouth News. "Women were more likely to be motivated to think about homosexual sex when their levels of progesterone were higher. Compared to a control group, men's homoerotic motivation was not increased by priming them with sex but thinking about friendship and bonding caused a measurable change in their attitude to the idea of having sex with other men."

Women were more likely to be motivated to think about homosexual sex when their levels of progesterone were higher.

Originally posted by Jack! Well, I actually don't believe we're totally born gay. Don't get me wrong it wasn't a choice I made, but technically you don't know sexual attraction, like real sexual attraction, until you hit puberty. And as a child you're not there yet. Your body doesn't know the feeling attraction to say "I find that man hot" or whatever. You're talking about 12 years of brain development and nurture that potentially effects your adult life completely, so there's every chance.

I was interested in guys when I was a kid tho. Tbh it was always a part of me and I entered my puberty early. Back then I didn't knew that the world (or even my own family) was homophobic so didn't even care about it. It was always normal for me but then I realised it wasn't so normal and that was the moment when I thought about it and heterosexuality but I'm still gay.

Btw. wasn't there a study in Sweden about the gay brain? I believe that our brain is just different or something. I don't think that it has anything to do with the environment, the father or the family in general. People are born gay, straight, bisexual etc. It is what it is.

I always liked men, but I had no concept of sexuality which is the best thing about being young and stupid.

Originally posted by iHype. I've always thought sexuality was all society and psychological. Like I just don't think anyone comes out the womb with it predetermined in their brain they like dick or vagina… Not to mention there's plenty of people who find out sexuality late in their lives or realize attractions for a gender they never had after marriage and kids. Like it's not a simple "born this way" or "you choose to be ____". It's really an individual person by person thing.
