I did try waxing my stuff once several years ago, luckily there was a bar right next to the waxing studio! It was a very interesting experience bantering with a very hot girl who was handling your penis, testicles and then turned you over to do your butthole. I remember one of those "Riiips" where I stopped talking in mid sentence. She said, "That one hurt, huh."
I loved it for about a week, then the red bumps set in and i started on some Keflex, to no avail. The rash seemed to last forever, I was thinking that any benefit that I got from having a smooth unit was lost by the unsightly red rash. So now I stick with the beard trimmer.
My wife got waxed regularly for a few years, and it permanently altered her bush. Now there's a dead spot right where her landing strip would be.
The biggest disappointment in waxing is when they tell you not to have sex for 2-3 days. I though that was the whole point!
