I don't have a hot wife but I chose to get a vasectomy. My wife had been on birth control pills for a long time and it was starting to make her skin blotchy and have other side effects. We were done with having any children so I decided to step up.
Everything I heard about it wasn't bad, an "in office" procedure, some discomfort. The few guys that shared they had it done said it was a little like being kicked in the balls.
So, one day I found myself lying on the table in the doctors office. I've got the ridiculous gown on that exposes your backside. The doctor comes in and asks me if I want a local anesthesia. He said not everybody does but I might want it. I of course jumped at the offer and said yeah. He gave me a shot of something on my nuts and said he'd be back to check on me.
He came in later and the anesthesia was doing it's job. I was a little woosy when the doctor told me something close to this, "Do you know that thing where a ...... takes a day off school to see what their parents do for a living? Well, I was wondering if you'd mind my ...... and some of her girl scout troop come in to observe your procedure." I was slack jawed! Then he bust out laughing and said he was just kidding me!
I relaxed after that and it was a snip, snip and a little burn smell from the cauterizing. Other than that no big deal except for coming back to the office to take samples to verify the success of the procedure. That was little awkward too.
