For this question I am referring to males who you don’t know at all or are just friends or co workers that you have no emotional desire for.

For males it’s different where just a quick look at a nice ass can start blood flowing to your cock.

I have to believe with females that when they see a very good looking fit guy that they occasionally fantasize about that guy being on top of them fucking their brains out.

I guess our DNA is set so females are much more selective as to who they might consider mating with, but I wonder how often they think about it and what actually is a trigger point for them.
