Vaginal dryness at 22 ?

I’ve been with my boyfriend for 5 years now. We had a baby boy in 2023. And he’s the only man I’ve been with. But even from the beginning I’ve been experiencing dryness. Sometimes more or less and sometimes on the right day I may not be experiencing it at all. But more than likely I’m dry down there. I also have never really felt pleasure from sex at all. I don’t feel anything bedsides him literally moving in and out of me. I don’t even know what sex really feels like. It definitely has to be something wrong with me at this point. I can tell that sometimes he doesn’t enjoy sex with me. I really just don’t know what to do. About two years ago I did bring this up to my doctor and she literally just ignored everything that I said. But I do feel pleasure from oral sex or anything that has to do with my clit. I just don’t feel anything internally I guess. Has anyone experienced this? Or have any advice?
