I tried making a Reddit account and it asked me to build karma before I could ask on any of the relevant subs so I'm posting here.
I can personally say that if anything goes up there, it hurts, and not in a good way. It does not feel pleasurable at all. It feels kind of like placing a finger on an open sore and pushing down.
Also, if you're being examined, they tell you to take deep breaths, as if they know that anything going up is going to be painful. If sex is supposed to be pleasurable and enjoyable, why would doctors tell you to brace for impact, so to speak?
Lastly, women often scream during sex. It's often said they're screaming out of pleasure and not pain. But there are a lot of things I find extremely pleasurable, but I don't scream while I do them.
Is it just one of those things that is painful but we're conditioned into believing the pain is actually pleasure and I must have inconsistent pain tolerance and I am making a big deal out of this?
Men have to worry about pregnancy too. If a man gets a woman pregnant, it's ultimately her choice whether to keep the baby or not, so the risk is she would want to keep it and you gotta help raise the kid or pay child support.
It sounds like you're coming from a perspective of women only having one night stands. In a loving long term relationship, I hope that the answer to questions like "does this guy have a wife", "is he going to hurt me" or "is he just using me" would all be no.
