Well it was for a good reason - I was at a charity event (Aid for AIDS, Black and White party) and was with work folks so had to keep it fairly classy but still be true to myself and the event.
Mr. S Leather makes a fantastic leather jockstrap. Very comfortable, soft supple leather, and a contoured pouch to really cup and and accentuate your goods. I wore it last night all night under my kilt and it was comfortable and sexy.
