In my own defense:
A) When i was younger? We didn't DO anal, and we SURE didn't talk about it, so you were pretty much on your own for dreaming up perverted stuff.
B) i tend to look at things from a "cleanliness" point of view, and will almost always opt for the semi-sterile, bacteria-avoidance types of thangs.
and C) tbh, i couldn't imagine sliding a vibrator up someone's ass, and then having to CLEAN IT, afterward...
Cram-pax fit in with my "If i don't monkey around in SHIT, i probably won't be a shitty person" philosophy of life.
So there.
