What are the signs?

To answer your question, it's actually quite hard to tell if a man (or woman) is gay, because the signs are not always visible to the naked eye. There are some men and women that I know that act completely str8 and love to do things like everyone else, but believe me, if you engage in conversation with the individual, they get open up and tell you quite a bit. I say though, never assume about that person because you could be completely wrong and that could screw up everything. I guess, if you want to know if a guy is gay, ask him about how he feels when two women are together or ask him intimate questions concerning a woman or her anatomy. if he has a disgusted look on his face, then you have you're answer. hope this helps you.

Are you looking for someone to say a limp wrist and a lisp? Because thats not any sign.

A gay person can act completely straight and the same witha straight person acting completely gay.

But You would look for no sex with wemon and no attraction for wemon. Getting out of situations that involves sensual closeness to a woman. Also you should be able to tell when they are uncomfortable with a situation.

Its hard to say. Watch their swagger and certain phrases they may use and watch who they may be eyeballing

ask him..you can't really tell by "signs"
