Short of them telling you or making the fact public, there is no way to discern whether a person is bisexual or not. If you really feel the need to know, ask them privately, but accept they can and may refuse to answer or lie.
Ask them if they are or are not. It's the only way.
The only way would be if he had sex with another guy or he told you himself. otherwise, it's just all talk.
if they have sexual intercoarse with men and women
The only way to tell is to ask them.
Ask them.
I would tell your bisexual friend that even though its hard to tell them but you have to because you're his friend. then nicely tell them that the other guy isn't interested and that there are better people out there for him.
Well, if its a guy, and he is shanking a woman while another guy is shanking him...
Words mean nothing. Show him. Then take pictures.
Unfortunately we live in a world where being gay or bisexual is not always socially accepted. You do not want to put this guy in an awkward or uncomfortable position, whether he's gay, bisexual, or not. If you know the guy personally, talk to him first. Tell him your intentions. If he is not consenting to your kiss, then you must accept his wishes and find another guy (or girl)!
just tell her to stop checking girls out, and only have eyes for you(guy).
Yes. Bisexual means you are interested in both sexes - male and female.
There are no signs. If you are bisexual, no one will know for certain unless you tell them.
She is still considered bisexual.
it does not matter that there bisexual it only matters that you love him
'I'm bisexual'
No. You are only bisexual if you are attracted to both men and women.
suggest a threesome with another guy and see if he says yes, most men find threesomes with another guy disgusting unless they're gay
