What happens when you need to have a piss? Can you imagine standing at the urinal & removing your dick from it's protective plastic cup?! Lol! :biggrin1:
Its not anything like that.... errrm.... imagine sticking ur dick and balls thru ur boxers... and keeping that way.... but a layer covering.
Briefs, tho... IDK about the booster kind.. I always found a thong did way more than I intended... since my mother couldnt stop staring at x-mas dinner 2 years ago.... kinda gross!
