Why do so many guys today hate wearing briefs?

Because briefs are constricting which makes them less comfortable than briefs.

I wear Y fronts Master Shaun. ;-)

Not in style anymore and women don't like em either

Some men view briefs as underwear kids wear like fruit of the loom. Boxers look more manly mature. Another issue is briefs can be tight at times. And a man wants boxers so his "junk" can hang loose in a pair of slacks

I haven't worn any underwear since I was 15.

They hate the fell of briefs.

Some of us like to freeball not have tight ball stranglers thank you, you'd understand if you had any knackers.

I wear briefs. Boxers ride up my crack and bunch up my leg.

My boys need to breathe

they choke our nuts....
