Perhaps this is geared more toward the guys, but have you ever turned down sex, whether from your significant other or someone else, and why did you turn down the opportunity?
I just posted a picture in "Sexy Hanging Boobs". It was a picture of a woman on a pool table.
The picture reminded me of a night following a party that my wife wanted to have sex on the pool table in our basement. I told her "no". She was very persistent but I wouldn't do it. I suggested on the bar, the couch, the floor. She insisted it be on the pool table. I was concerned about the table being made unlevel. (I take my pool playing very serious). Once we got upstairs, I made my move and, as expected, was told, "You had your chance."
For the record, we did eventually do it on the pooltable, multiple times in fact, in the years to follow.
There were a few other times I denied her, I'll add them later.
