I just lost my virginity to a guy I didn't really like
Why would you sleep with someone you don't really like?
Because I heard it's not easy to lose. And also, I wanted to give it to someone who would really care about me
Wanting to lose your virginity is understandable, but you shouldn't be in a rush to do so. If your first sexual experience is bad it may turn you off from sex in the future.
I'm sad you are making me feel bad about my choices, but I would want to do it again even with someone I don't like if they were more attractive.
Anyway what happened cannot change so I suggest you to have sex with someone you really like.
