I agree with Boeing although I am considerably older. The purpose of initiating this topic was to generate a constructive exchange to provide female insight for aggressive males who often may mistake what they believe is sexually attractive to women and to inject a healthy dose of realism to temper what may be pure male fantasy.
From my discussions with women, their primary attraction to a male is for their security. Unlike other species, a woman not only seeks physical protection but financial and emotional well-being and a good-looking, healthy, intelligent and loving gentleman who can also provide these necessities will probably be more successful than a brute with a big cock and nothing else.
But there should also be a distinction between IRL situations and what ladies may fantasize about which may release their primal passions when watching 2 males in a physical contest for their favor. Both are rational female desires and are compatible.
Of course, I'm just a guy and this topic is intended to encourage insight from more female members to help us males get a clearer focus on what ladies really find arousing.
