Had it done years ago. They gave me two pills to take 30 min before the appointment. Mrs. and I were doing some shopping that morning. I got more and more messed up as we shopped and she finally sent me to the car. Sat in the waiting room at doctor's trying to act sober when I realized I was on a perfectly legal high. It got more fun for a while. When they finally took me back, the pills were wearing off. I told the doctor about it and he said they'd give me a little something else. "Something else" turned out to be a needle in the nuts. Not good!
During the procedure, a nurse who happened to be a friend of my Mom's walked in. Uncool !
A month later, I had great pain on one side due to some kind of infection. I thought I was dying! Antibiotics put me right in no time.
All in all, I'd do it again. It takes all of the worry out of the grown-up thing.
More like a sock monkey, really...
