It's sounds like you may be bisexual. A lot of girls have a phase in which they "experiment" with other girls. But you seemed to have liked it a lot, which makes me think it's more than a phase.
You have to ask yourself -- are you attracted to girls? Like, would you ever wish to date a girl? I think you are bisexual, but you really have to ask yourself and find yourself to find the answer.
Well obviously she is bisexual and/or lesbian. What you're feeling could be hormones, adrenaline, or lust. What do you feel about her now (do you like her, do you still see her as just a friend?) If you begin feeling an attraction towards her, it could just be because of that night.
If you begin to start getting attracted to the female gender altogether, you may be bisexual. Just play it out and see what happens! You're probably not bi, but just acted on the moment, and went with everything because it felt right.
If you WANT to be bi, tell your friend that you liked how that night went, and you hope to do it again. If you DON'T tell her it was a fun night, but it should stay your little secret. If you don't know, just see what she says!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
