I remember the first time I read about a provider offering DATO during a session (I was in a different province and it was not as open minded) I was kind of shocked. I can't imagine doing it to an SO so it was hard to imagine putting my tongue in a strangers bunghole. Not judging at all, just hard to understand. I don't enjoy receiving, it feels weird to me. and it's true I have a mental block with men's butts but I do think it's a really important area to explore.. I just personally am not big on it giving bum pleasure, which I do think is a bit unfortunate. Oh well, there's always toys.
But mouth and anus don't go together as far as I am personally concerned. To each their own. But I don't get it. Lol
