I have no experience with this and I do not believe I would want to take part, but I am not one to judge! To each is their own! I was just curious about it though. What is it? Why do you choose to do it? When did it start? What type of gratification does it carry for you--sexual, happiness in general, comfort, or what?
I'm just curious. I do not want to put anyone down or anything like that. Just want to learn about it, since it is part of this site and all.
