OK. time for a funny (but true) story.

Many years ago (That's a prelude to excuse bad behavior), I was with a prostitute and things were going along just fine. Then I guess she came, 'cos she suddenly stopped and said we were done. I said 'I'm not finished'. She started pushing me away and said we were finished. So, having a reasonable amount of self control, I stopped.

Then my sense of humor kicked in and I started laughing. Actually at that time I needed the laugh more than I needed the sex.

The moral is...

Even a prostitute has a right to say no at any time.
