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?
You should definitely see a doctor about this because it does sound like a problem.
But,
It's also possible you just don't like sex. You might be on the asexual spectrum. Your vagina might be reacting like this because you just don't want to fuck. Or maybe you'll fix the medical issue, be able to fuck, and then decide you don't like it. Nobody can know if that's gonna happen but you.
Talk to the doctor, figure out what the problem is. But please don't feel pressured to enjoy sex. If that ain't you, well it doesn't have to be. Besides, there's lots of ways to have a fun naughty time other than penetration.
