There are no signs. If you are bisexual, no one will know for certain unless you tell them.
'I'm bisexual'
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.
Same way you can tell if a straight man likes a girl. Usually they would admit to it, it act like they have a crush on that person
Well, if its a guy, and he is shanking a woman while another guy is shanking him...
Two ways. You can go up to random people and say 'Hi, I'm a bisexual' Or you can do it subtly. You can find a friend you trust and tell them, or you can let a little conversation be overheard (or a text message read) by a gossiper (the best people for the job). There are also many more ways of doing this.
A bisexual is someone who is physically, sexualy and emotionaly attracted to both boys and girls. There is no real way to tell if your girlfriend is into you. If your girlfriend is not kissing you or doing sexual things with you, it doesn't mean she is not interested, it could mean that she is shy, or has insicurity or a personality disorder. Try talking to her. If she isn't a lesbian or bisexual then she usually wouldn't be dating you.
If you fall in love with and is sexually attracted to both genders you are bisexual.
they find out that they're bisexual and if they think you are good friend and not a gossip or jedgemental then they will tell you i know because i'm bisexual and if anyone is gonna ask how i know this is my answer i had a crush on a male friend in yr 5 and i have a girlfriend now
You can tell by the gender of the person/people you are attracted too. And if that's still confusing, you might be bisexual.
