Sexual compatibility and waiting for marriage, is it something I should expect when doing things that way?

18M here and to me it feels unlogical and even stupid to wait until marriage and place expectations or even hopes that depends on my wife to give me the experiences I've waited a possible life time for. It's like you're setting yourself up for failure and disappointment and I'm saying this broadly for whoever does this and whatever they want in their intimate life considering sex may he important to you in marriage. Does waiting until marriage mean giving up your sexual wants and desires completely? Is that the cost where even after you're finally married there's still a high chance you still won't get what you want?

Think about it like this, wouldn't it be quite uncomfortable for your performance or simply likes and dislikes be dependent on someone else's happiness and satisfaction? I got a feeling some people will say "you should be happy in Christ, and my friend let me tell you, you 100% can be happy in Christ and thankful for what you have but still be dissatisfied with the sexual component in a marriage. It is it's own separate thing. Some people want to experience human relation and intimacy the way THEY want to before their time is up on this earth.

I am NOT trying to be a snake when I say this as I'm coming to be more educated this is just my point of view right now. When Jesus comes back and we go to heaven human relations will never be the same, so why strip yourself away from the beauty of what he created for you, with the desires he pre destined gave to you just to "not sin" when we're already sinners?? Why leave it up to pure luck and place your sexual satisfaction needs on your partner and stress them with that or even leave room for it to be a problem in the first place?

I've been thinking a LOT about this and I don't wanna go into a marriage disappointed because she doesn't meet expectations or satisfactory I waited years for and hurt my wife with that in the process. Or even vice versa!! I'd be completely and utterly destroyed if my wife didn't like sex with me and didn't enjoy it or I didn't live up to a dream or expectation. I'd rather get sex out of my system, check off the bucket list where it's not a priority anymore and I can focus on other things besides that like finances and our emotional connection and relationship and MOST importantly our children. And if the sex is okay it wouldn't be the end of the world and I wouldn't be so defeated thinking about all the beautiful intimate pleasurable things I could've experienced but I gave up for what purpose..?

I've been search and looking for answers and nothing is convincing me to continue down the path of waiting until marriage.
