It Is Just Fun ?

Sometimes it is just fun to jerk off, I love jerking off and I know that you do to. So why are we ashamed to do it? When I woke up this morning I found a houseguest doing it, as I walked past her on the couch where she was sleeping, I was also fondling my morning wood. We looked each other in the eye and she turned a strange shade of red. She spent the rest of the day saying she was sorry and that she does not do such things, that she knew it was wrong to God, and although she has tried to stop she just can't. I felt sorry for her. I told her it was ok and that we all masturbate, and that she should do it more often.

I come from a liberal family, so why is it wrong to have fun?
