This also includes camping. The best thing about coming outside is the delicious worry of being caught while you're at it. The world is full of beautiful places to have sex, from beaches to forests to mountain tops to fields of hay. Date a farmer; he'll show you how to make glorious love against a hay bale. Or marry a mountaineer; they'll introduce you to unfamiliar terrains from a whole new perspective. Coming outside means having to be a little bit quiet (no shouting for you; otherwise wild bears might attack), and also being careful about sun burn/insect bites/nettle stings/sand in unwanted places. Still, being at one with Mother Nature and letting him bring you to the peaks of sexual desire makes for a thrilling ride.
I love Stephen King and music festivals; I eat my toast upside down; I daydream about getting married probably a bit too much; and I wish every day for a pet sausage dog puppy (who never materialises – sob).
