lmao, damn I forgot about fun time with ice.
Well unless you are a big time massochist, you can try out my b/f's dumb yet almost could work method:
When you are preoccupied with something and want to stop, bang your head against a wall, really hard, or some other sensitive body part.
You now have to think about your massive headache, or other boo- boo, and why in the hell you would follow the instructions of a smart ass.
It will definately take your mind off of orgasms for a bit.
