The shape of the human penis is that way in order to remove the soft plug of semen of other males from the vagina. This implies that women are sluts and men who often get sloppy seconds had more children. A dog's penis has a knot that swells up to lock it in place so that other dogs can't screw the bitch at the same time. Apes have a tiny penis that is solid and they also have a hard plug for their semen that basically cements the vagina up so new semen from another male can't get through. Cats have a barbed penis to help secure themselves inside the vagina so that other males can't get in and screw at the same time.

Trivia fact: there's a separate hentai manga for each and every one of these and many more.

Well literally yeah. It's why you find boobs, butts and thighs attractive, male brains are programmed to look for indicators of femininity, and the most visibly obvious of those are signs of high estrogen. The reason most people stop finding women attractive past a certain point of body fat is because your brain registers their proportions as being more babylike, which you know to avoid when searching for a partner.
Testosterone on the other hand is the male sex hormone, it strengthens and lengthens bones, builds muscle, encourages risk taking, aggressiveness and possessiveness and the sex drive. Ever wonder why men are stereotyped as perverts? A healthy man has over 15 times as much testosterone as a woman, while women barely even have 6 times as much estrogen as men. Men are actually much more equipped to deal with the heightened sex drive that comes with increased testosterone, which is why woman with even twice as much testosterone as a healthy woman [still only two fifteenths of a healthy man] are often much more lustful than other women, they've got no natural means of handling that much [hence why butch girls tend to talk about sex so much]. Men on the other hand are not equipped to deal with increased estrogen, which comes with its own problems.
