First off that sounds like one awesome party! I have just recently went through the same problem. I was questioning my sexuality for the longest time.
I wasn't sure what I liked. I had kissed many girls at parties and playing games but haven't gone further. The main question I always asked myself was, DID I ENJOY THE KISS?
Or in your case did you enjoy the sex? I enjoyed all the kisses. And thank god we played in the dark cause I could feel that my cheeks were getting red.
Personally what I think you should do would be to start talking to your friend more. Hang out with her more stuff like that, and find a way to give it a second shot to see how you feel.
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.
