My man actually has a bunch of pairs of the male lingerie Eden is stocking now. (We both gravitate towards the sheer stuff that's a bit revealing and sexy.) But neither of us would touch this pair with a 10 foot pole. To me it isn't sexy it's just kind of dumb. I couldn't take it seriously, even if my man wore it I don't think I could possibly find it sexy or a turn-on.
If my man wore these, it wouldn't end the night for me because I love him and love our sex life. But I would ask him to remove them immediately and then try to get the visual out of my head as quickly as possible.
I am certainly not speaking for every woman on the planet though.
But I'm sure you already knew that.
