Thongs

Tried 'em and the front was a bit snug (almost trapped) but the crack felt like I tied up a bale of hay with binder twine. Wiggled for hours until I went back to commando.
 
Thongs are my normal everyday underwear. Has been that way for 10 years.

Yeah, me as well. Once I tried them and did not find them uncomfortable, it became everyday for me. First day it felt odd for maybe an hour, then totally forgot about it. Been that way since.
