Every woman is different, so I don't mean to speak for all women when I say: I don't find sexy men's underwear or swimwear attractive. Now, that's now to say I don't enjoy seeing men's bodies, but there's something about sleaziness that turns me off. I never enjoy male strippers, except on an ironic level. Maybe a pirate... but, I digress.
Here are three examples of items I don't ever want to see a man wearing in real life:
a unitard
Whatever this thing is
A sarong; for the love of God, gentlemen, never wear a sarong!
