Saving two or three seconds makes a big difference in an emergency!If you are really dying for a piss you'll never get it out in time
Never happens, at least with briefs. Maybe with woven boxers with no button in the fly.It can be uncomfortable if it slips through the opening & rubs up against a cold zipper
Only if you wear them for several weeks at a time. Try changing yours more often.The bottom of the opening will collect lint
Maybe, but most briefs without openings sell for more than those with them.It must increase the cost of the underwear due to excess material and sewing
