How to talk about my sexual dissatisfaction to my bf of 2 years?

I'm really happy to be with him, and I wouldn't even want to refer to making love as "having sex" but things are getting somewhat frustrating for me. For most of the time we have been together, we were going with the flow and not talk about sex. He would often ask me if I had an orgasm and would be bummed if I didn't. I told him that none of the things we were doing are stimulating my clit and that these questions are somewhat pressuring me for the next time... Flashforward several months, we decided to talk more openly and give feedback. For whatever reason, I was the first person to teach him that female orgasm is pretty much centered around the clit. (I don't understand how he doesn't know that since he is 7 years older than me, 33 -I blame it on porn) He started to pay attention more, after that talk, but now we are back to "the routine" of doing things the convenient way. Anyway, I don't want to sound selfish but I don't like the fact that I get to have an orgasm maybe 1 out of 10 times. I don't want to make him feel bad as well because he will feel like he can't satisfy me or he is not enough for me... or something like that. Any suggestions would be appreciated.
