Orgasm issues

Okay so my boyfriend and I have frequent sex. Great right?!? Not so much. Lately i don't know if it's me or him but I haven't been able to climax. He usually does before me. Now that I think about it I have pretty much always been like that. Even with my partners ( only 3 honestly) before him. I've faked orgasms before just because it would get awkward at times and I would feel bad. I've brought up the issue but I feel like we didn't get anywhere. Any suggestions on what I should do?
