A few years ago, for Halloween, I dressed as a musketeer and my pants were 2 sizes too small and I had a 12" dildo shoved down one leg. Obvious bulge, obvious outline. We were at a bar (with my wife right there) and I can't tell you how many women came up to us, started flirting with my wife *while* grinding on the dildo.
Society is so hypocritical. One day, the OP's picture will be socially acceptable. I see no difference between that and a woman showing a cameltoe. If she's hot, the toe's plenty hot. If she's ugly, it's gross and inappropriate.
