I am not talking about attraction but a turn on. Wet panties.
I won't bore you with words like confidence and assertiveness. I am not here to sell you a book.
The turn ons are,
Aggression
Other women
A male would fight or flee an aggressive male. A female would fight or befriend. A physically aggressive male releases oxytocin in a female. Oxytocin in short is the bonding chemical; the stuff that makes mothers care for infants and panties wet.
Women are turned on by criminals, fascists of all sorts, drug dealers, psychopaths, vampires, werewolves, soldiers physically. In movies women have more sympathy - oxytocin - for the villan than the hero. A borderline psychopath like the Joker is sexually attractive. A violent rapist is more likely to give orgasms than a hard working-9-5-guy.
As a man do you dream of submissive rape sex ? But women do.
All the body building essentially makes you attractive because you can beat the shit out of her. It's the veiled threat that is attractive. If she can not submit to you in some way, she is not attracted to you.
Female lions survived by submitting to the aggressive males and friending them and killing of weaker males. Aggression releases oxytocin. There is no fighting nature.
Women are also attracted to women. If you embody femininity along with all its nuances you are attractive to women. This can be seen in sigma males like Russel Brand.
