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?
I probably have vaginismus and my experience with penetration is pretty similar to yours.
Cis women do enjoy and even seek out vaginal penetrative sex, I eventually realized. Part of how I figured out I was different was reading a thread of all the weird stuff women inserted while masturbating. I was suddenly like: "Oh! They must really want something up there! Look at the stupid, dangerous stuff they're doing to experience that!"
There are things you can do medically if you genuinely want that kind of sex, but it's useful to remember that sex isn't just penetration. You literally never have to be penetrated to have enjoyable sex. It can be tough to find a partner, since PIV is the end goal of sex for lots of people (as is their perogative), but the world is also full of other types of people.
As for vocalization, the "oh fuck" (doc, it's like sandpaper ripping me in half) and "oh fuck" (I'm having an overwhelming but positive physical sensation) are pretty different kinds of yells, and generally sound pretty different. Like people don't cry just out of sadness, you know?
