I've had it done to me many times, and it does feel good, and it's one sure
fire way that the guy is gonna get some ass. ;)
But I don't reciporocate, because guys just aren't that conscientious about
their hygiene in that area, I'm also not into men's asses.
Couple that with the fact you can contract Hepatitis A, B, and C; Chlamydia,
gonorrhea, urinary tract infection, HPV, herpes, and conjunctivitis, means I
most definitely ain't going back there.
I'd recommend a dental dam, that way you can have the "cakes" and eat
them too.
