How to make sex enjoyable?

I’m pretty new to anything sexual and I haven’t had the greatest experience with it. I just feel like there’s something wrong with me, maybe I’m just not capable of feeling pleasure? I don’t know my own body at all, I’ve always been very scared of masturbating so I’ve never done it. I have no idea what feels good. I’m currently on birth control which took what little sex drive I had completely away, so maybe that’s my issue. Sex just doesn’t feel good, I’ve never felt any good feeling, just pain. What pleasure I have felt last for a second and goes away like that. It’s mostly pain or no sensation at all. I don’t know how to fix this issue. Any suggestions?
