Trouble coming during sex or masturbation

Hi girls,

So I’m 18 and at the end of last year i lose my virginity to my boyfriend. We have been dating for around 6 months. When we first started I only let him finger me and it felt so good, after a while we finally had sex. But the thing is It didn’t feel as good as I thought it would. Tbh I couldn’t really feel him inside of me. Ever since then when he fingers me or when we have sex i can’t really feel him in me and get no pleasure out of it. Mind you his penis isn’t small if that’s what you all might be thinking. And when I’m real horny it’s the most annoying feeling ever. I always make him finish, but I have never finished and only about a week ago did I try masturbating. (I have never tried masturbating before nor have I watched porn) and I only tried masturbating this time because I couldn’t stand not finishing this time. Anyways that didn’t help I couldn’t finish then either.

Do you girls have any tips or is there something I can do I’m so desperate. With masturbating and sex with my boyfriend.
