dear internet,
I recently went on a trip to visit a friend and ended up losing my virginity to said friend. He was really nice about it, and didn't pressure me into having sex, but afterwards he kept acting weird. He wasn't avoiding me per se, but the vibe I'm getting is that he thinks we made a giant mistake and also that I'm in love with him, which I'm not really. I'm REALLY scared to bring this up to him in casual conversation, but I feel kind of like a cheap whore and I don't think he knows that.
It's killing my self-esteem and making me freak out. What in the world should I do?
