Might as well do it all
Will Ferrell on Shaving, a true statement? If a man shaves his arms and legs he might as well shave his vagina too. I think it is, and that goes for those who shave their chests and nether region as well. The only excuses for a man to shave anything but his face is to please his old lady (Honey, your back hair has whole communities living in it. Shave it please) or if said hair is extremely unsightly, see aforementioned back hair, or if it causes a risk or harm or for a medical condition. That’s it. Anything else is feminine behavior and plain weird.
