I'm going to editorialize here for a minute.
In the desert, being a young single guy can be a great time (being a young single female is even better... you basically have your pick; all the action you can handle)... but be careful. It's only natural that when you throw a few thousand hormonally-poisoned young people together in the desert far away from home, things are going to happen. Here are the rules: Be careful, don't get caught, don't get pregnant, and don't get infected. If any of the above happens, and you get disciplined/pregnant/STD'd, don't complain; you were warned. Take your lumps like a grown-up.
On a related point, as a married service member, engaging in infidelity and promiscuity in the desert marks you as an idiot. Don't do it... you're risking your career and your marriage. In the internet age, "What does TDY, stays TDY" doesn't exist anymore. People email pictures and videos home... it's a small world, and an even smaller military, and people will talk. Don't count on anything being a secret for very long.
I saw it every time I deployed... fraternization, stupid promiscuity, married guys acting like singles, attempting to score some action on the side, etc. Some got away with it, but for others it came crashing down.
My all-time favorite was the herpes outbreak we had at one location. I had this married TSGT crying his eyes out in my clinic at the fact that he'd contracted herpes from this airman he'd nailed (like a true idiot, he used no condoms, and his junk was covered with vesicles). We were under GO#1, so there wasn't even any alcohol he could have used as an excuse to deflect the blame for his bad judgement. He tearfully asked "what am I going to tell my wife?"
I just looked at him and answered "yeah... what are you going to tell your wife? You'd better come clean, because when she eventually comes down with genital herpes, you'll have some 'splain' to do. And you'd better hope she doesn't get an outbreak when she's having your next child, because that could endanger your baby." I let him think about that for a minute, then hooked him up with some Acyclovir and pain medicine, and sent him on his way. I know it was harsh, but those are the facts. I don't understand why otherwise intelligent people choose to blow their lives and their relationships apart with decisions like that.
There is plenty of sex in the military, but use your good sense. You don't want to be that individual who gets off the plane on the flight line, only to see an attorney waiting at the bottom of the stairs with divorce papers.
