I've been married (and divorced) three times. While I was married to Wife #2, we decided that I should get a vasectomy. And, of course, when I say "we" I mean "she."
I went to the doctor and set up all the preliminary stuff and scheduled it for a Friday. I told my wife on the way home that I had to be shaved before I get to the clinic because they don't do that for you. My idea was that she could take care of it for me and we could have some fun out of it. Of course, she was not interested. "You can do that yourself!" she said.
While we discussed my vasectomy, I told her not to mention it to anyone. It's no one's business but ours, I figured. She agreed.
A couple of days later, I come home and her best friend from across the street, Nancy, was there and they were laughing about something. When I got closer, I found out what it was: they were laughing about my upcoming vasectomy. My wife also pointed out that I wold have to shave myself because she damn sure wouldn't do it for me.
After Nancy left, we had a big argument. She was of the opinion that telling Nancy was okay and didn't violate our agreement not to tell anyone. Whatever.
A couple of days later, I was at the mailboxes and Nancy approached me. She said, "I know you're upset about her telling me, but I have to admit that it's always been my fantasy to shave a man. I've never had the chance because my husband won't let me. I was hoping that you'd let me do it for you."
