Can we please agree that the need to procreate isn't. A. Kink.
It may be a sexual desire, but it is the prime directive. It's why you want to fuck in the first place. To procreate. Acting like that's a kink is like proclaiming how you're going for a different kind of thanksgiving dinner and it's still a turkey.
@Wezzah no. I disagree.
humans like dolphins or bonobos fuck for fun or stress relief without the wish to have offspring. So in my mind the wish to produce (a lot) of offspring can actually be a kink or "hot" to some people.

@cat_unbridled i agree with @Wezzah . the fact that humans and certain animals fuck for fun means that they have a certain degree of consciousness such that they are able to do beyond their prime directives.

i have sex for fun, and i have lot of fun with sex, and I don't want any further prole. rationally it's 100% fun.

the complex desire system that our body creates when we want sex, screams prime directive.

I don't have the same when i play board games.

but I have similar desires when it goes about food.
#fear is another good one. it's so complex and articulated meant to protect us from death
