advice please

I don't know what it is but I think I'm one of the few people who doesn't think sex feels good, like when his thing (I hate saying vulgar words😂😂) is inside me. When he licks me out it's really good and anything else but apart from that sex just doesn't feel good and I don't know why does anyone else have this and is the anything I can do, I sometimes get pain too and this just isn't to do with being pregnant it's ever since I had sex for the first time I always say I'm gonna go to the doctors but have other things on my mind
