If you want to try it just do it, who cares what others think about that... you really need a label like bi, gay or whatever to know if you want to do it or not?
I dont think it make you bi ... like other people said even if it make you bi who care?? I think people are free to live their fantays as long it legal .. and no one is abuse or stuff like that !
if you want to try you go right ahead and don't fry your ahead about it afterwards... enjoy it, great a new interest, don't like it, well just don't bither again, but you at least tried!
