Interestingly, there has been a lot written about vaginal tearing, cuts, and irritation as the result of heterosexual intercourse.<quoted text>
You are still trying to equate the two?
So dr. does vaginal intercourse have the same risk of ripping the vaginal wall as anal intercourse does tearing the anal wall?
Son, learn the difference between risk and inherent harm.
You should look it up.
Maybe you should ask your wife. Or maybe not... You may not like the answer. It could be that you're not "adequate" enough to make a difference down there.
