Somehow I feel its much, much more than this. To me the use seems to encompass an almost spiritual essence. It is embroiled deep within ones soul, their very being if you will. When I contemplate one who I feel exudes sexuality, it far surpasses anything in the physical realm. Perhaps Imerely am putting to much emphasis on the act itself. Strange stuff in my mind it is. Have you never seen someone who seems to just exude sexuality? I encounter these magnificent creatures in both sexes from time to time and God help, I want to be with them, almost as if I am a leach seeking to prey off whatever it is they have. Strickingly oddly however, I sense the same aura about myself but not in a full time capacity. It seems I can turn it on and off at will. I have exercised it at gatherings and found it to be effective enough that it almost always assures me of getting laid. Seems others can sense it also and better, they respond to it. Maybe I'm just micro-managing the definition down to such an exact aplication of the term it doesnt even seem to fit? I dont know but it ALWAYS interests me when someone uses the word "sexuality" in reference to themselves, I must know if they are using it in the broad, vague sense society seems to use it or in the deeper, spiritual, unexplainable sense I percieve it at. hmmm... maybe more another time.
