I've mentioned on here in another thread that I've always found high heels to be a major turn-on - either seeing others wearing them or wearing them myself. I can walk in five-inch heels without any problem these days and I don't feel I'm really dressed unless I've got a pair on.

As for having sex while wearing them... definitely. I'm quite short anyway, so if a guy is taking you from behind and you're both standing you really need to be wearing heels otherwise there's going to be a height problem
