In case it wasn’t mentioned already, consider looking into pelvic physical therapy. They specialize in this area and treat physical problems that cause pain during sexual activity, bodily functions, etc. I see one and it has helped me a lot!

My wife has had an issue with pain during penetration that turned out to be caused by the depo birth control shot. It’s a rare side effect that no one told her about.

Sitting is not only superior, it’s also optimal for proper urination. This is not my opinion. A pelvic PT professional told me this. I only stand rarely. Mostly when I’m in a public restroom with a urinal.
