Panties...normal...white...boring panties. Though I believe I've spent the last little while wearing men's boxers for whatever strange reason. You have to understand that my clothing choices have always been a little adverse.
As I grew up I wore tightie-wighties (or is it wightie-tighties?) more or less because that is what my parents bought for me until age 10-12 when I started with boxer-briefs, which is what I am currently wearing. I feel they provide both a good amount of comfort and support for my massive package and me.
