sexual awareness

since working in a highly populated job with alot of hot good looking females around my age,I have noticed that I have been alot more keen and in tune with my sexual awareness. I have always been aware of this and always known that girls almost always go for the guys with a keen sense of sexual awareness and how to trigger sexual attraction in them almost magically..well,not really but it seems as if it is so.
You walk in a room,she catches your eye and as if by magic you get those warm,
giddy sexual feelings and it's as if you two are engulfed in a little bubble of
sexual attraction,well it's kinda like that for me anyways lol.

I was just curious,how do you girls do it? I mean,can you really tell if a guy is
sexually aware or not and if he is not does the door slam closed forever? even if
he is a good looking guy or is that a free pass lol.

There have been many instances where out of the blue I have been soo sexually aroused for no reason at all and I turn around or even a far at a close
distance I catch a young lady checking me out,almost as we were in the same
sexual state or something,not sure how to explain it in words but it feels like
either she became aroused and somehow trigger arousal in me even without me knowing it consciously but it happens anyways.I have never experienced this phenomenon so
much as I do now..strange but really intriguing.I have also noticed that many times
standing near one or working near one,I feel heat coming off her and it's as if
there is a silent (though powerful) sexual attraction or tension between us,no spoken words no direct contact but it's there and I feel it.

Not sure what to do with all of this and not sure how wise it would be to act on
these feelings,say asking one out to dinner or something.Maybe attractions exists
merely on the basis that the chemistry is there but not nessessarily a connection??
