I think briefs on a man are one of the most unsexy garments he could wear. Particularly the cheap patterned ones you see at the market. I think it's the combination of the feminine style of a high-cut leg, with the fact that nothing is left to the imagination. Even David Beckham couldn't carry them off in that famous advert (in my opinion anyway!).
It makes me wonder if any blokes in relationships actually wear the things. Do any of your men wear them? And do you find them sexy? I think it would put me off any form of bedroom activity!
Give me a man in boxers anyday....
