As far as a first date goes, one should wear (or not wear) whatever makes them feel comfortable, both physically and mentally.

Since the subject of ‘sexy’ underwear came into the discussion, sadly, what many women perceive to be ‘sexy’ underwear, many men don’t. Obviously, men won’t tell women that, especially if it means the difference between being laid or not! I happen to know that Mr Darkhorse has never, ever seen any so-called ‘sexy’ underwear (either in a shop or on anyone) that he particularly liked or turned him on. A stray wisp of pubic hair poking out from the side of a plain pair of white M&S knickers, or a lady wearing French knickers, boy-briefs or command do it for him every time.

i prefer not wearing any

I like to wear my oldest pair of boxers with the perished gusset. It allows my nuts to hang free and 'breath'.

I prefer wearing none under my skirts.
