I was at my psychologist today, and we were talking about possible bottom surgery for me, and doing a little small talk about the general subject. We have a very good relation, and conduct most of our conversations in German, because she wants to keep it up after she had studied in Austria.
Anyway some transgender folks (MtF) seem not to now very much of the female genitals they plan to get. She had several of her patients wondering how they would urinate, once they had their penis chopped of! She had two of her patients wondering, if females urinate through their clitoris, and were wondering how it would work with them, because they don't have a clitoris. Others were wondering if their anus would become their vagina!
She said that about 1/3 of her patients do not really know how that is with a vulva, clitoris and vagina!
And one can see again, there are no dumb questions!
