Oh, they are interested. Military guys get caught up in romance/blackmail scams all the time. It is a big deal when it comes to security clearances/background checks. They occasionally go out to bars, usually at the behest of their married friends. A single guy with a well-paid government job just isn't a winner these days. Our unit padre told me about a "singles" event organized amongst some local units/churches a few (10?) years ago. Total disaster. 4:1 male/female ratio and many of the women who showed up were not technically single but rather "going through a divorce".

You got that backwards. Teenagers are horny and want a "romantic" life in the bedroom. Once they get older they slowly lose that drive and finding a partner requires a huge amount of "activation energy".
