TUMA means Tongue Up My Ass. I don't want anything up my ass, period. I have to endure annual digital prostate exams and that's not at all pleasant for me.
That being said, if you are dining on really great pussy, I have yet to find a woman that doesn't like some light starfish tonguing mixed in. No penetration, just light touching with your tongue and/ or mouth. There are a lot of nerve endings there, just like the pussy and taint. If it is not spotlessly clean and hair free, I will not go there.
I would be open to some light TLMA (tongue licking my ass) while receiving BLS and BBBJ from a woman. I make sure my azzhole is spotlessly clean, along with the rest of my body, before any session or civie sex.
