One major problem with screwing outdoors is MOSQUITOES! When my wife and I were dating, she went down on me in a drive in theater. Since it was hot, we had the windows open. You can guess where I wound up with a mosquito bite...right where all that blood was concentrated and under pressure. Hope I made the mosquito fly off and explode! Of course, it meant I had an itchy welt on the tip of my dick for several days, meaning I had to scratch it very unobtrusively! She, on the other hand, never got any itchy bites.
Then there was the time we were camping our way across country, in a van we'd converted ourselves. It was pretty cold outside, so we stayed in the sleeping bag we had in the van and I got between her legs. We had a beagle those days -- a very stubborn, but lovable girl. Normally, as soon as I put a hand on the my wife, the beagle would hop off the bed and leave. I guess she didn't like having her sleep bothered. But, this time, it was too cold, so she refused to budge and I wound up screwing my wife with the dog between my feet!
