Help!

Hey guys!

So my boyfriend and I have been having sex for about 3-3.5 years now, we lost our virginity to each other. Every once in a while I'll get frustrated that I can't orgasm, but he can finish. He recently started feeling really bad about it, but I just can't no matter how hard we try. We've tried fingering and oral but I can't and I feel bad about it. Any tips or tricks? Is it impossible for me to orgasm?

Thank you! 😊
