how can you tell if you're bi?

[Chey-Chey]

so i have a boyfriend, and i love him very much, and i wouldn't leave him for the world. but i have thoughts about doing things witht girls sometimes, and i've told him about it before, and he isn't mad about it an dknows im not gonna do anything. and i look at girls all the time....like how cute they are and stuff....i have this whole thing in my head about what "my type" of girl is.
i WANT to act on these feelings, but i DON'T want to at the same time. i know i won't. but im just confused. so does it sound like i'm bi to you? or is it just me being curious? (been about a year of me thinking these kind of things i think)

You probably aren't bi. You might just be curious. Alot of people at some point in there teen lives will have these feelings. You are only bi if you try to ask a girl out or do sexual things with a girl. Even then, if it's only once, it satisfies your curiosity, and you don't want to do it again or continue to go out with a girl then you're not bi. You're only bi if you date or want to date or have sex with girls more than once or twice. Judging from you saying that you wouldn't leave your boyfriend or actually go out with a girl then I don't think you're bi.

I've only done things with girls a small handful of times, yet I know I am bi because I have always fancied women, sometimes more then men. I am with a man now, and I have only had one girlfriend in the past.
Anyway, I would say you are curious - like some people are as young people, I identified as Curious for a while before deciding - It's good your bf understands and isn't annoyed - that is a good start.
If you ever need to chat about it send a PM, if you like.

Hey,

I'm not sure what kind of help I can be, because I'm sort of in the same situation. I've always wanted to be with a guy, but I have sexual feelings towards girls as well. But the way I see it is that a relationship is a lot more than the sexual feelings you get for the person. It means that you can be emotionally drawn and attached to the person as well. Can you imagine an intimate relationship with a woman the same way that you can with a man? Just because you can imagine having sex with a girl or you like the idea of it, doesn't necessarily mean that you want a relationship with a girl, and if that were the case then I wouldn't consider you bisexual. To be fully attracted to someone, you have to look at them in a sexual way and in an emotional relationship sort of way. Just my view on it anyway, although I'm sure not everyone would agree.

This may not be the response you were shooting for, but I'm sure your boyfriend does it all the time, not meaningly. I think plenty of people do it, but not intending to cheat, or like someone else.
Just to state that to think about other people and their appearance is quite normal, although could possibly ruin a relationship if it gets out of hand.
