I can’t cum 😢

So I’m 20 years old and my body count is 9. I’ve never been able to orgasm with any of my sexual partners and I’m not sure why. I have the birth control implant and I am also on antidepressants (have been since age 14). I’m not sure if those would be a cause for it? It’s very discouraging to me. Sex still feels good for me but there’s no climax.

I’ve been with my boyfriend for a few months (known him for about a year) and he told me the other day that it makes him insecure that he can’t make me cum. I want to be able to for my own pleasure but I also want to so that I can make him happy. I love my boyfriend and I don’t want him to think that it’s his fault. Please help
