Hylas and the Nymphs. John William Waterhouse, 1896.
Go for a Swim
Piggybacking off of the last idea, you could go swimming and get your sexy on in a pool, lake, ocean, or river! This is a little bit riskier because it is less likely you will be able to guarantee privacy unless you have your own pool and some high fences or own land that involves some sort of water feature. Either way, having sex in the water is a semi-public experience and although the thrill of potentially getting caught could be, admittedly, very fun, it definitely has its risks. Please consider how private your situation is, the risks involved, and prepare for your forays into outdoor sex!
Change Up Your Positioning
One good way to relieve how much heat you’re siphoning off of your partner is to change up your positioning so that there is less bodily contact. This can mean everything from simple positions like doggy style or more complex, creative, and challenging positions. Make a game out of it! How much fun can you have with the least amount of contact?
Detail from The Happy Accidents of the Swing or, The Swing. John-Honore Fragonard, 1767.
One great way to minimize contact and even get you off the bed and literally suspended in the air (so you can put fans underneath you, naturally) is to get a sex swing. Sex swings can be as simple as a door swing or as complex as one of those fancy ones that anchor into the ceiling. They can vary drastically in price from relatively cheap to “you spent a month’s worth of rent on a sex swing?!” Regardless of how fancy and complicated you get, sex swings can be a great way to keep everyone cool and can help you achieve more complicated positions if you’re lacking in the flexibility department.
Move Somewhere Cooler
If none of the above works for you, you should just move to somewhere that is temperate or just straight up cold all the time. Like Siberia...or San Diego.
