Honesty, intelligence, morals. Want to land and keep a man or boyfriend? Play hard to get. Have high morals. Men respect that. If a guy leaves because you say no, you did not want him in the first place.
Sure, if they need too. Some men have big breasts. If they don't, there really is no need to. They are uncomfortable.
They are much more comfortable than cotton briefs designed for men. Boxers offer no support at all and look awful.
I would think if you could pick 20 guys at random and make them drop their pants, I think at least 7 or so would be wearing panties. Just a guess though.
Roses Dept. Stores have great Granny panties, they are Carole brand. Nice wide crotch. Really a great pantie for guys. Very comfortable. Roses Dept stores are down south along the coast. Eastern shore Maryland, Virginia, North and South Carolina.
