talk it out

I might be bi, and am not sure this is forever: is it wrong to have sex with her?

I'm a 17 year old male currently involved in a relationship of four months. I'm a virgin, and I am also "questioning" about my sexuality, but my girlfriend is unaware. There was a time when I would consider myself bisexual, because I am attracted, physically, to males but not emotionally, but I'm still not entirely sure that I am bisexual....
