Im not sure if im gay! , do you think is a good idea if i try with a guy? where can i meet gays in miami ?

first off , don't have with a random guy. If that were the case you may as well have with a prostitute. Go to Miami, have FUN. Got to local gay and straight clubs. I'd say find some you like, be it male or female and be intimate with that person because you like him/her, not because of their .
