How important is sex?

There is this guy with a very genuine interest in me. We have the best times when we’re together. He is very observant and I feel like he gets me and truly sees me for me. He enjoys my quirks which is a huge breath of fresh air. But I have a big concern when it comes to our sexual compatibility. We are not on the same wavelength. I am very sexual and have had many sexual partners, so I know what I like and what gets me going. To me, sex isn’t necessarily tied to romantic feelings. He has had considerably fewer sexual partners and doesn’t have sex unless he’s emotionally invested, which I respect and admire, we’re just different in that regard. Another thing is what we like in bed. I am turned on by intense sensuality and prefer rough sex (though I also enjoy slowing things down and relishing each other). He’s not like that, and when he does it I can tell that’s not who he is and he’s doing it to please me because I have been vocal about the importance sex has in my life. And I understand that people can adapt and things can be learned, but there’s a little more than that. I hate to be this person, but his size is not enough to satisfy me. I am used to several orgasms in one go, but with him, I have never had one. I am deeply afraid that if I decide to really pursue something with him, that the “just okay” sex will present a problem later on.
