Advice?

So I'm my boyfriend's first, well, everything except kiss, and I recently realized he's "one of those." He's "not into" going down on girls or nipple play or period sex which fine I can get over, but I also don't think he knows that the female orgasm is a thing. When I was experiencing my firsts, I did a ton of research and talked to my partners to try to understand their bodies better, but he's just not doing the same. Do you have any advice for how to talk to him about what I want/need sexually?
