Very interesting, hadn't really thought about that. I've had 20 years if clenching/straining/pushing, so who knows what that might cause.
Another thing I've noticed, at least today, is that I might be having a bit of difficulty with urination now. I notice that during my attempts to empty, I won't urinate, or even have an urge. After I stop trying, especially if I have a little luck, I finally get the urge to pee, but nothing happens! A few times I've had to wait for my whole " lower section" to calm down before trying to pee again. Strange, and a bit alarming. Even while I sit here typing, I have a tiny urge to pee, but if I mentally try to push ( for urination), nothing happens. Thoughts?
