Best gift I get (every year now) is a new set of Saxx underpants. They're great.
One of the big things I've learned in my 35 years of life is that a little splurge on anything you wear near your dick and balls makes the rest of your life much easier to bear.
I picked up a pair of Andrew Fezza brand boxer pouch brief, once. They were absolutely amazing. The fabric was a smooth stretchy/silky feeling stuff, almost like a compression garment, but not tight. They lasted 20 years of washing before the elastic in the waist stated to give up.
I haven't seen them for sale since.
