What makes someone gay

Being attracted to a member of your same sex and not the opposite would be my definition.

From what I've heard, there's actually an evolutionary reason for it. Homosexuals help their siblings with their children, since they won't get any of their own. Thus increasing chance of survival.

A lot of things; genetics (appears to account for about 33 percent of one's likelihood), the amount of sons a woman has, her overall health while she's pregnant, as well as possible cultural and social factors. Most social animals, to a greater or lesser degree, are capable of homosexual activity, or otherwise have some degree of members of their populations that are homosexual. In fruit flies, a particular gene can make males engage in courtship behaviors with one another; they sometimes form circular conga-line type things which each other.

Cum tastes great. Salty, sweet, sour…. Mmmm

It's the chemicals in the water turning the freaking frogs gay!

But honestly I don't know, though i've heard theories about how it has evolutionary advantages.

When they've got their cock in another man's arse.

I dont think theres any one reason I think there's a host of things that causes it.

When you've got your cock in another man's arse

i think its when a guy likes fucking guys. im no expert. i dont think they like girls if they're gay.

The desire to be sexually intimate with a member of the same sex is what makes a person gay!

What "makes" someone gay?
I think gayness is a real-turn-on masturbation technique for those with sexual frustration. I don't believe people are born gay homosexuals, they are abusers of their sexual ability and take the wrong path to make them happy.

Since you're kids u hang out with the same gender to play, look at any school yard. Even as adults people tend to stick to their own genders. The only time genders mix is when the need to reproduce surfaces. Either than that, men and women aren't made to be mixed. Heterosexual marriage is an invention that people tend to follow by fashion, which is fine, but it's fake.

pretty girls turn other girls gay, simple.

Liking the same gender as that individual, but also participating in sexual acts with them

Genetics/evolution. There's a lot of research saying we're more on a spectrum than just heterosexual or homosexual. There's no one gene that makes someone straight or gay but multiple genetic factors. And unfortunately for some, childhood trauma can be an influence on their sexuality and understanding of what sexuality is. Kinda like how kinks are created. (First sexual experience/ turn on involving something specific)

Hair dye. Doesn't matter what color, if anyone in your family dyes their hair in any way, all newborns will grow up to be gay.

In reality, probably a ton of random stuff. Could be influences in utero, gay sperm (men who dye their hair make 'em every time), and/or early-life events (trauma, strange interactions, "don't be gay" lessons, etc).

Turning gay later may or may not also be a thing, though it's my theory that the later in life you discover your sexuality, the more likely it is that something is going wrong or has gone wrong in your life.
