Youll see a thingy poping through his pants
he was gay and horney
The only way to know is for him to tell you.
Then you leave him, because he's gay.
You can't
If you are a boy and he is dating you he must be gay or bisexual. If you are a girl and he is dating you what makes you even think he might be gay?
if you are attracted to anouther boy you are gay. If you feel like you want to kiss them than you are gay
if he hugs you all the time
if it is a boy he is gay but worry tell your other friend
Well if you are a boy and are attracted to a boy then you are gay if you are also attracted to a girl you are probably bi which means that you like both genders. Same for if you are a girl.
Feel his crotch, or just ask him!
It's basically the same process as a boy and a girl,there is no difference
The other girl would have to be Bi, Gay or Pan.
