I'm not a virgin and I'm totally stoked. It's as amazing as everybody says it is.
The heat isn't much at all compared to the typical humid Virginia summer, but, it's a lot more arid, and the hotter it gets in the daytime, the colder it gets at night, so don't forget to bring something warm. (goggles and a bandana, too, for the dust storms.)
Also, don't forget to start drinking water before you go, because the dust will -really- dry you out. Also, the baby wipes can be your best friend, and vinegar water in a spray bottle is REALLY nice on the playa feet.
