Don't really have on at the moment, kinda gone off women (as I do everytime one disapoints me).
I suppose I could describe the last;
Fantastic long legs (she often wore dresses or skirts), beautiful long brown/black hair (very dark, recently got a bit lighter but still dark), very cute smile (she looks self conscious when she smiles, dunno why but it does things to me, especially when it's in response to something I've said/done). Umm, what else, hips were fantastic...big, bright eyes (she'd stare me down and it felt like she could see inside me...or whatever... I liked her eyes, ok? I don't have to justify it) nice boobs (not too big for her figure, but big enough to draw my attention). She also looked tall from a distance, but when she was right next to me she'd have to look up (I dunno if this is normal, but I like staring down into a girls eyes, but at the same time have a thing for taller girls...just not taller than me).
I daresay the next girl I become infatuated with will be somewhat different, the last few have all been dark hair, light skin with bright blue/green eyes. I don't think I'd have even noticed how stunning that forementioned girl is if she didn't take an interest in me first..
