That's a pretty hard question. Even harder, i'm guessing, to deal with first encounter.
I think sex &love are often very very different things. You may connect with one sexually, but be completely out of sync emotionally. Or I do think you can find "the one," but totally miss the ball when it comes to a sexual relationship. It could that whoever isn't enjoying it may not be
ready for a sexual relationship.. I don't know.
My boyfriend right now is amazing. I've been with him for over a year &a half. We broke up once. &in the first time we dated, I just didn't enjoy sex with him. It wasn't because I didn't love him- because oh god, i've known he was the one since the start. But for some reason.. Sex just wasn't good. We broke up, got back together, &in the time we had been apart, i'd matured a lot. Figured out a lot of things within myself, &overall just grown a lot. &i had just grown a lot more confident. &the first time we had sex when we got back together...
wow. it's been amazing since them.
So it is possible to be with "the one" ¬ have the best sex. It will most likely cure itself with time. Just look at yourself emotionally. Try to strengthen yourself or something.
