It's a common complaint from men that women lose interest in sex after marriage. I lost quite a bit of interest sooner than that, though. When I was young, I couldn't wait to have sex. I thought about it a lot, it seemed like it would be one of life's greatest experiences.
But single guys and now my husband always wanting it, tricking me into it, complaining they don't get it enough no matter how much they get, it feels more like something to run from half the time. (yet I put out nearly every day!)
When something is over-available it always gets less exciting. It's even worse having something pushed at you over and over at times when you're not in the mood.
What if women kept begging men to cuddle with them, whether they felt like it or not, disregarding what mood the guy was in, or what else he was planning to do in the moment. Punishing them by pouting and arguing when they say no. And never being satisfied with what he gave.
I bet after a while they'd HATE the thought of cuddling anyone, ever.
