Sounds like he is trying to find a comfort spot to confess a little secret.
You don't... if you love her. Just ask her, if she doesn't want to, find another girlfriend because she is not truly bisexual in that case.
she maybe bisexual or gay but you might want to ask her. Then move on to next^^
'I'm 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
Depends if you are a boy or girl searching for a girlfriend.
Yes. Unless your girlfriend is bisexual, and her best friend is bisexual or gay.
If she says yes when you ask her or if she leaves you and get together with a girl, which also can mean she is bisexual. If she is a lesbian she would not be with you (if you are a male asking).
don't just choose a girlfriend based on whether they are bisexual... but girls tend to be more open about their bisexuality (it still depends about where you are...but in NY most people are open about their sexuality)
We can not know that and thus can not provide you with an answer.
You ask her.
Depends on the mood, tone, and setting of when he asks. If he asks randomly then perhaps he is trying to find a comfort spot to reveal his secret.
I would imagine so. My girlfriend is not bisexual. I wish she was actually. If she was bisexual I would a much stronger interest in marrying her.
