Because men are bigger porn addicted horndogs than women. Porn addiction leads down a spiraling hole when the normal becomes bland and you need ever increasingly exotic and depraved fetish material to be stimulated.
That is true.
Also if you have 10 males on 1 female, the courtship dances become a bit annoying for the females.
Especially if the males have only their private parts to show, expecting they will woe a female with a measly, tiny, blurry, low effort dick pic.
