Men say that women are so privileged because they can get sex anytime and they (men) would love to have it, that women are selectors. And ignore that sex usually not pleasant at best, and painful or dangerous. They want available sex for their bodies, where orgasm is almost always guaranteed, they are in control of what's happening, they are not the one who are being penetrated, they can stop anytime, there is no risk of pregnancy, there is no pain. Guess what? I think under those conditions more women would want sex too.

Same thing about dating, women are selectors, take your pick. Cool. And how usually relationship looks like? Usually it's a woman, who takes care of household, and takes additional tasks in her life and then if we talk children, it's even more prominent. While for men that means that he would work as he did before, but come home to clean house, to food in the fridge or even cooked, and will be praised if he plays some sport with his kid once in the while.

Men simply bring less to the table (in general), and that's why they are ones who are more interested.
