Yes, I agree they often are susprisingly non-whoreish. I know a couple of SLEs who, though they clearly enjoy the chase and like knowing (er, believing?) they *could* sleep with whomever they want, won't get with just anyone. These two are both late-twenties now and seem to have grown out of their youthful playa days. Mostly
When it comes to love, *real* love, they do take it very seriously.
