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

Most people would need a mood to be set to enjoy sex or to be ready to receive something. Think this applies for women and for men who partake in anal sex.

By that I mean they need to get turned on to feel like having intercourse, because yeah, intercourse is strenuous and requires your body to be in a specific mode. For a penis inserter, getting turned on is a much simpler affair and can happen in a matter of about 1 second.

Lastly, women often scream during sex.

I don’t know if they do to be honest. A lot of pornstars do, hahaha - they’re paid to ham it up and overall they give an unrealistic view of how sex works. (Once upon a time the main watchers of porn would be people who hadn’t had it yet. Possibly still the case)

Uhh despite my initial dismissal, i’ll suggest this: some people might do it because sex can be akin to tickling, where your nervous system gives you mixed messages or gets overloaded. And, some women exist who grossly exaggerate their “noises” during sex, believing it makes it more fun or gives an ego boost to the husband. It probably can make it more fun for both parties, but the authentic noises - no matter how quiet they are compared to screams - are great as well.

Can’t really speak for the experience of having a vagina but if it hurts so much that you don’t ever feel like having sex, and haven’t self stimulated in any way, talk to a doctor about it?
