… Yet even when methods have scientific anchors — for example, when studies show (as they have, repeatedly) that an active sex life contributes to the overall health and longevity of the human organism, and they’ve got the medical evidence to prove it — there is still the question of the researchers’ assumptions about sex. Researchers’ biases, in terms of how they think people should respond or what they believe should be normal behavior in bed, distort the data they report. Nowhere is that clearer than in recent studies which have concluded that fucking is good for you. Don’t get me wrong: fucking IS good for you. If you like it. If you’re not that into it, it’s not so hot.
What researchers are less inclined to admit is that it is not the act of fucking itself that is so healthful: it is the arousal and orgasm. Arousal begins the process of the brain sending out those lovely and delicious chemicals; suddenly, our hormones are jumping to attention and informing every molecule to prepare for a thrilling event; our heart rate increases, our pulse quickens, our blood rushes into our genitals, and ultimately orgasm completes the experience, with its own complement of swooningly sweet brain chemicals and, finally, deep relaxation.
Fucking is just one of untold numbers of ways that human beings can produce the above effects. Which is why celibates may enjoy all the same benefits of sex as the fuck monsters, provided they masturbate. Actual male/female intercourse doesn’t add health benefits, except in two ways. Fucking requires a good bit of energy and coordination and is reasonable (though not great) exercise for toning and stretching muscles (including the ones between your legs and buttocks). If you never work out, fucking may be the least you can do to stay in shape, though, frankly, yoga is probably better for you, with less chance of accidental injuries or strains. For women, maintaining vaginal health and flexibility after menopause requires some form of penetration — though not necessarily by a penis. So if you want a happy vagina, put something inside it and move it around. Of course, that could be your lesbian lover’s strap-on, your favorite vibrating dildo, or that shampoo bottle you secretly molest in the shower. (Do I know my readers, or do I know my readers?)
… The truth is that even if you’d rather go to bed clutching a shoe than a partner, even if you’d rather fuck the laundry than a member of the opposite sex, you can still enjoy all the positive health benefits of sex, as long as you get aroused and have orgasms.
