I cant orgasm with my boyfriend and I LIE ABOUT IT

So, my boyfriend (25M) and I (21F) have been dating for over a year and I have never had an orgasm.
We have sex quite often, about 3-7 times a week, and I CANNOT get there. It’s getting really frustrating, I usually wait until he falls asleep and finish myself. I’m really confused as to why this is happening and how to make my VAGINA WORK!!
I’ve never been able to finish with any partner. Him and I have talked openly about what feels good for me and he does spend a lot of time doing those things. I can get close to orgasm, but never…cross the finish line. I can finish by myself, or when he’s asleep, but not while he’s awake (masturbating next to each other), or while we’re having sex or when he’s fingering me/eating me out, or whatnot.
I was raped as a teenager, so I’m starting to wonder if that has anything to do with it. I know for sure it’s a mental block though considering I can finish alone just fine! Anyway, has anyone else experienced this/have any tips??

Side-note: I felt bad for him because he felt like he was doing a bad job, and I got into the BAD habit of faking it… so he has no idea I’ve never finished. I know it’s bad!!
