Becasue you haven't seen literature means that you haven't sought it out.
Sex is used to sell shit because everyone has sex, even when done poorly its still good. Few ski, and even fewer do it well. Still, the economic impact of skiing in the US alone is in the billions of dollars.
Skiing can be done from an early age well into advanced years. We have an 85 year patroller at my resort; he's had both knees replaced.
Skiing can be done by yourself, with a friend of any sex, or with a group, all without sin. You meet new people while skiing constantly.
Skiing is done outside, in the sunshine. If you do it well and folks stop to watch and cheer you on.
A ski day lasts at least 6 hours.
Skiing keeps you in fantastic physical shape. You rarely see an overweight person skiing, and never see any obese ones.
You can compete with others in local, regional, state, national or international competition. You can join a club, meet more new people, and form lasting relationships that allow you to get together and ski.
Sex is used to sell shit because everyone has sex, even when done poorly its still good. Still, the economic impact of sex in the US alone is in the trillions of dollars.
Sex can be enjoyed from ones teens well into advanced years. 29% to 25% of people over 80 are still sexually active.
Sex can be done by yourself, with a friend, or with a group. But it is best done with some you love.
Sex is done outside in the sunshine, inside when its raining, and can be enjoyed year round. If you do it well, and are into that sort of thing, folks stop to watch and cheer you on.
Sex lasts as long as you make it last. And since its done all year, can provide more hours of entertainment.
Sex is good exercise. I never see an overweight person having sex, and never see any obese ones. (I don't look) Sex is good exercise for people with physical limitations and handicaps.
You can join a club, meet more new people, and form lasting relationships that allow you to get together and have sex.
And whats more.....
Sex is a beauty treatment. Scientific tests find that when women make love they produce amounts of the hormone estrogen, which makes hair shine and skin smooth.
Gentle, relaxed lovemaking reduces your chances of suffering dermatitis, skin rashes and blemishes. The sweat produced cleanses the pores and makes your skin glow.
Lovemaking can burn up those calories you piled on during that romantic dinner.
Sex is one of the safest sports you can take up. It stretches and tones up just about every muscle in the body. It’s more enjoyable than swimming 20 laps, and you don’t need special sneakers!
Sex is an instant cure for mild depression. It releases endorphins into the bloodstream, producing a sense of euphoria and leaving you with a feeling of well-being.
The more sex you have, the more you will be offered. The sexually active body gives off greater quantities of chemicals called pheromones. These subtle sex perfumes drive the opposite sex crazy!
Sex is the safest tranquilizer in the world. IT IS 10 TIMES MORE EFFECTIVE THAN VALIUM.
Kissing each day will keep the dentist away. Kissing encourages saliva to wash food from the teeth and lowers the level of the acid that causes decay, preventing plaque build-up.
Sex actually relieves headaches. A lovemaking session can release the tension that restricts blood vessels in the brain.
A lot of lovemaking can unblock a stuffy nose. Sex is a natural antihistamine. It can help combat asthma and hay fever.
