Partly you are right Xhonzi but gender ideals are largely cultural and open to the fashions of the age.
Culture and technology can frequently replace and overwrite what may be biological cues.
When poor people had to do manual labour on a spartan diet the idealised woman in western culture was heavy and pale because rich people could afford lots of food and didn't have to do exercise outside in the sun.
If a wealthy woman couldn't eat enough to get that shape or obtain that skin tone she wore padding and painted her face pale.
When poorer people had access to cheap food and took up more sedentary work indoors the ideal changed to being lean and tanned.
Rich women had the time to go to a gym and the money to travel to the sun. Once again if a wealthy woman couldn't naturally adopt that shape they had to resort to cosmetics and corseting.
As travel and gym access became cheap the idealised form became emaciated and pale and dressed in extreme clothing which would normally look ridiculous but could go in and out of fashion and promote the spending of money.
When women can't keep up with that they take drugs, starve and cut bits off of their bodies (in Africa women spend a lot of money bleaching their skin with harmful corrosive creams in the west women spend money and time risking skin cancer under sunbeds).
Breasts are interesting because in a lot of cultures they are not sexualised at all and in some large breasts are seen as ugly and just as some women risk their lives making the breasts look ridiculously large others spend similar amounts cutting them off and removing the natural fat layers around the hips and thighs.
Human bodies are seen as commodities and while men's bodies have traditionally been seen as less so it's increasingly no longer the case.
You can't move around the web without seeing an advert flash up offering a fast track method for making a normal looking man look like a leather armchair.
Action heroes tend to be athletic to make the action seem plausible but also tend to follow the idealised form of the day.
So it's unlikely that a Rubenesque action female would sell cinema tickets (unless as a gimmick) but the same is true of an overweight male action star.
Western culture doesn't have an equivalent to someone like Sammo Hung anymore (unless the actor was once very fit and attractive but has been cast for nostalgia reasons).
