No, in fact it's impossible for a straight guy to turn gay for any reason.
Yes gay guys have sex just like any other people who want to do so.
No. A person who enjoys sex with both guys and girls is bisexual.
Gay sex tend to be more intense and lasts longer. I assume you're asking about guys with erections. Basically, they bring each other to orgasm. There are lots of ways to do this, depending on what they like. They can masturbate each other, one of them can put his penis into the other guys anus or mouth, they can have oral sex at the same time (called "69'ing") -- there are lots of possibilities, and the best thing to do is experiment and tell each other what's fun and what isn't!
No, it is only gay if the two guys have sex.
No. You are only gay if you are sexually attracted to members of the same sex.
No. They don't actually turn gay. In an all male environment such as prison or the military, many men will turn to other men for sex. There's nothing unusual about this: most guys are capable of homosexual acts, even if we don't usually do it. Sex may also be used to dominate or humiliate another man, which is rape, of course. There are gay virgins, of course, just as there are straight virgins, who may discover their sexual orientation in such places. But the fact is, if you weren't gay before you went into prison, you won't be gay when you get out. (But you may have to admit to yourself that you're bisexual!)
They turn out to be gay mostly when they are attracted to members of the same sex, and then decide to come out.
People who fancy the same sex.
No, not at all. You are only gay if you are sexually attracted to members of the same sex.
Umm CREEPY but most gay guys having sex do erm anal?!
They don't turn gay because sexual orientation is unchangeable, but there is no choice if they want to have sex.
