Well... if being skinny is a meaning of being sexy, then...
...She's been, and always will be so sexy for me, even if she were actually fat. I'll always see her enough skinny for my tastes!!
She's simply too cute to be labeled in that "mundane world of skin and fat".
I saw a lot of turn-ons on her (some about specific areas of her physique and other about her personality, which are actually sensual and perhaps sexy).
So I can avoid her weight so easily, just to fall in love with her , by her voice or smile!!
If I were blind, I'd also love to be embraced by her (both naked, LoL).
