During our first proper meeting, we ended up having drunken sex in the backyard of the party we went to. It was my first time with another girl and I loved it. After that night, we continued to have sex and to see each other.
I felt myself growing actual romantic feelings for her, but at that time I was scared and unsure of my own sexuality. I worried about what other people would think, so I stopped seeing her.
I still feel incredibly bad about it. But now years later, I can say with absolute confidence that I am bisexual and that's nothing to be ashamed of.
