Do women really even like sex or not.......?? or it's a chore to keep their partner? (seems too much like it)?

In every culture around the world, all I see is men craving sex, and women looking for anything but that. It's always the men advocating it, there's no male prostitutes around, but many women ones...why not for free...?...I don't know any guys who would not do it for free Heck there's men who will go to 3rd world countries to have sex with 3rd world protitutes.....but I never see women do that....
But some people (mostly christian conservatives) point out a view of a man in a woman being made for each other, I see it as a formula for disaster (I think the world would be a better place if we were asexual..).....even in relationships the man is always the one asking for sex, and the woman acts like it's a chore. so do they even like it?
Please be honest, i'm trying to figure out about my sexuality, i'm tired of being lied to....Because part of it is: I wouldn't want to be in a relationship where I know my partner's not enjoying herself/himself

Update : A relationship like that would make me feel uncomfortable
