Well that's a bit of a silly question to ask . Gay guys like boys/men , straight guys like girls/women. simple :)
No, there is no physical difference between gay and straight men.
Yes, there is. Tests have shown that gay men have different balances of hormones and different wiring in the brain to straight men. It is theorised by many that there is also a genetic difference, but there isn't yet any proof of this. Tests on women have been inconclusive so far.
Straight men generally do NOT chase gay women unless they don't know the woman is gay.
no, but it's possible that closeted gay men who pretend to be straight might do this.
Straight men are too straight to be gay. so dats not gonna happen to a straight guy wad ever his age be.
You don't. Just as gay men cannot turn straight, it's the same for straight men; they cannot turn gay.
Gay men wear the same kinds of underwear as straight men.
It's exactly the same as a man being straight. There is no difference in pleasure.
If your a straight man why would you have gay sex?
No straight person becomes gay. Ever. You are either born gay or you aren't.
It depends on how homophobic the straight guy is; nowadays, it is not uncommon whatsoever for straight men to have close friends who are gay. In fact, a friendship between a straight and a gay man can be very beneficial to both men, in part because they can have more candid, open conversations about a myriad personal topics than a straight man typically can with another straight man, or gay man with another gay man.
Yes. Gay men and straight men are the same anatomically.
