Firstly what reasons do you want to have sex? Sex is a two sided blade one side it's for pleasure, fun and can be filthy or just to kill boredom the other side of the blade is it's a tool. One for breeding, mediation or control. Which of these suit you and ask yourself why.
I'd suggest against casual sex with multiple people for a variety of reasons. Sex is a tool for breeding and ritual imo, meaningless sex is rot for the self. On another note if you live in a hot location like Nevada keep cool. Sex is very taxing I wouldn't want you to suffer from heatstroke.
