Ditto to the above poster.

Though it is completely possible to just be attracted sexually to the same sex and opposite sex without actually attaching a label to it. What i mean is, for me its more about falling in love - and personally, i could fall in love with a woman OR a man. Or both. Who knows? I'm pretty open and liberal sexually so that may taint my veiws some.

Personally, i think if you enjoyed your experience, good for you! As long as you are having sex for the right reasons and not the wrong reasons(looking to be loved, low self esteem) then whoever or whatever kind of sex you have is entirely up to you and the person or persons you have it with. And of course, stay safe.

I wouldn't focus so much on the label - just leave yourself open. Just think of yourself as a sexual being, not a BIsexual or HETEROsexual or HOMOsexual.. just sexual, like all of us are!
