I wouldn't promise that activity to anyone until after we've met and I've considered the person and our chemistry.
Have I done it? Yep. Do I love it done to me? Oh yes.
But boy ... that is a YMWV (your mileage will vary) activity if there ever was one for me.
And I don't even know your name! Why would I share with you if I do this or not?
Seriously. Do you really wish to put your mouth on an area, and say that you will, and you don't know if that person has hemorrhoids (you can be clean and have growths there). No, thank you.
So if you want an honest answer, you're going to have to bend over and let me tell you after I've taken a looksey. And then, maybe.
