Never getting satisfied during sex

Me and my boyfriend having been dating for 10 months now and he took my virginity the sex is always great but I never feel completely satisfied. I've never had an orgasm and he keeps trying to give me one but sometimes I get so frustrated I just let him finish. A lot of people say eating out might help but sometimes he's really good at it and sometimes I'm not really feeling it and same with fingering sometimes it hurts. I think a lot of it is me over thinking during sex but I can't help it. NEED HELP ASAP
