Sex... A very good exercise. A healthy active sex life is 1-2 times a week.
Pleasurable, and pretty much the only exercise America will vouch for... Haha! I'm just being a douche there. I really have no idea. I'm fairly young. Knowing the technical things really does nothing. Sex and Intercourse happen for many reasons and provide many things. Vague... vague. So very vague.
Reading the stories on Urban Dictionary shows me how depraved some people can really be. Reading here... Confuses me deeply.
Oral... Yep, I have no concept of that either.
