Back in 2008 I put up a video about women's reactions to getting a Brazilian wax for the first time. I followed that up in 2009 with a couple of videos of men undergoing the same procedure, and later with another video of men trying it for the first time.
I've just come across this clip of men allowing their girlfriends to perform a Brazilian wax on them. I should think it's a relationship killer, but . . . well, see for yourself.
I'd say if a relationship can withstand that, it's good to go!
