S.A. is harboring something which attracts. The person does not need long legs or shapely mouth watering bulges. The person could look like a dump truck, be dressed in a paisley mumu, and still have Sex Appeal. It is the look in the eye, the care in the light touch, and the way the person carries themselves as they walk.
I am sure there is a lot more which could be said on ths topic. I mentioned how it fascinates me. I often think I might have it. I adore flirting and most everyone seems to enjoy my flirtations. It isn't because I am thin and the stereotypical loved one. Maybe, just maybe, it is Sex Appeal!
