Making love in hammock feels more like dancing than making love. In a good way, I almost feel like the hammock becomes another partner, a twosome becomes a threesome as you're more readily subjected to gravity and movements are magnified and muffled. You'll get really turned on by this but eventually the hammock will become the focal point, this is where the problems arise. When I was having regular sex in a hammock it was a fun novelty but eventually my partner at the time and I realized that we were more attracted to the hammock than eachother.
