Um, FU*K NO!
My sister tells me all about it when she has gone to get BBW done. I am having none of it. Now, I thin the cedar, so to speak, but aint no one, NO ONE getting near my little guy with a bucket of hot wax or a steel blade. I'll trim my stuff myself. I do a good job. I also dont do it to look bigger. I have no problems in that area. I do it to keep things from getting too unruly down there. As I said before about belly buttons, if someone wants me to do any of that business with a blade or wax or whathaveyou, they need to buy me a house or something first.
And yes ladies, its common knowledge (in GQ and MAXIM) that a close shave can give you the appearance of an additional inch or two.
