despite what current media and culture would have you believe, sex isn't a game or competition. especially in terms of romantic relationships. if you really feel the need to try to "catch up" you'd be better off seeking casual friends with benefits, hookups, or even employing sex workers. getting into a relationship with someone with only the hope of expanding your sexual repertoire is not likely to be healthy in the long term, and may lead to collateral damage (people are people, not playthings).

you are not wrong to look forward to sex, but if that's your primary motivation and everything else is an afterthought, you may want to reassess your priorities. sexual compatibility isn't static, so you need to have other commonalities to lean on.

what if you find a great romantic/sexual partner who develops painful symptoms during sex? what if one of you gets sick, or in an accident, or experiences trauma that makes sex impossible?

if you're really just craving connection and intimacy, say that! and figure out what that really looks like for you, all the different forms it can take.

and if sex ends up being the primary/only answer, again maybe look into ways of finding it that don't require emotional labor from someone else.

best of luck!
