Sort of bring up what they think of gay people e.t.c you know do they mind them? do they think there treated right? then obviously depending on how close you are to this person, try and ask them if they would ever think of kissing someone of the same sex. or you could be like. (dude my friend was seriously drunk and i saw him makeout with a guy/girl) then ask what they would do if that happened to them e.t.c.
There is only one fool-proof method. You ask them.
The only way to properly find out if someone is bisexual is to ask them, or to be told by them, do not make assumptions on a persons sexuality because of the way they look or act.
You ask her.
sexual orientation cannot be changed. If someone is bisexual, they are bisexual for life.
Throw in a crate of beer! (LOL) Ask, never force someone or get them drunk.
you ask them.
Its not up to other people to answer whether or not their friend is bisexual. If you want to know someone's sexuality, just go and ask THAT person. Don't rely on other people. That's how rumors start.
You ask her!
you ask them.
you should not ask that
I like boy and girls what does that mean
It is not advised that you ask a person if they are "gay, bisexual, or just paranoid," as this is rude.
