To address first the issue of us having communicated in the past, your name seems familiar, but I cannot quite place you. Could you please refresh my memory? You wouldn't, by any chance be the man who lives or had lived in Hong Kong?

Now, to address the underpants issue. I like sexy underpants (and sexy swimwear) on men. I like them a LOT. But they've got to be MEN'S clothing. There once was a member here on SYD who had a huge wardrobe of sexy underpants which he was kind enough to model in photos he posted. His name was jumpramp and I called him the Underpants King. Alas, he's gone.

But as I said before, men wearing women's clothing, be it undergarments or outerwear, for me is a Major Turn Off.

And also as I said before, it's mostly straight men who do this. You are a prime example, as you describe yourself as "mostly straight". Gay men rarely do. About fifteen or twenty years ago our newspaper here ran a lengthy article on this very topic. There are (or were) stores that specialize in selling sexy ladies' undergarments to straight men.
