Chop - as far as why someone would want it - just about anything that can be thought of with sex in the domain is out there - that 757sex had some pages up on it back in 2003 according to archive.org - but they had a robots txt file that prevented it from being indexed so I cant tell ya what used to be there - last check by them was in Feb 2004.
I would imagine that someone might have had some pages going for terms like the mile-high club or something along those lines
