Most days, briefs - colors and patterns, not tighty-whites. When I can, panties are first choice.

I have and will again most likely - depends though on who he is. Not interested in just joining in on a group of certified disease-free guys. Good friends are possible. Just like licking pussy - wouldn't just jump into a bunch of women. . . Wait, who am I kidding, YES I WOULD! lol

Soft between 1 1/2 inches and 3 inches; Hard about 5 1/2 inches. So. . . big enough for the purpose.
