Can’t orgasm even though I used to be able to

When I was single I used to masturbate fairly frequently and would orgasm pretty quickly from straight up clitoral stimulation. I stopped masturbating a few months before I had met my boyfriend, no reason in particular I just didn’t have the time or feel the need to. However, once my boyfriend and I started dating I just can’t orgasm. We’ve had sex about 10 or so times and I still have never finished. I’ve tried masturbating again and I still can’t get myself to finish. He’s tried fingering me and it feels really good however I still can’t orgasm. What’s wrong with me??
