There women were living together. One Saturday night they all come home from dates, and they are chatting about dates.

One asks " how do you know if you had a good time on a date? "

So the first says, "well, i have a shower as hot as i can stand it, then if i come out feeling all warm and tingley, it usually means i had a good time."

The second says " me too, but i have the shower as cold as i can stand it, then if i'm shivering and shaking when i get out, it usually means i had a good time"

The first two women ask her "what about you?"

She says" well i have a system too, but it doesnt involve the shower. I come home, get undressed, through my panties against the wall, if they stick, i know i had a good time."
