>>11038634>I don't understand why prostate stimulation brings pleasure.Because there are nerve endings there. Your prostate is where you shoot semen from, it shouldn't be _that_ surprising that it's connected to sexual pleasure.
>And I don't understand why it has to be stimulated from the ass.Because it's inside your ass. It's human anatomy. It has to go _somewhere_, and it's a sensitive organ so it can't be on the outside. Also that's not entirely true, you can also stimulate it to some extent by applying pressure to your perineum.
>Shouldn't males mainly derive sexual pleasure from penis stimulation?They do. The majority of men never stimulate their prostate sexually, while virtually all men use their penis sexually either by fapping or having sex. Obviously there's no anal component to natural male/female sex either.
