When I was in the Army, we active duty females would occasionally be accused of romping with the married males while we were out in the field.
Imagine, if you will, heading to the Bavarian mountains (along the border of the Czech Republic, rather than the Alps, but still...) in January, when there's been snow on the ground since the beginning of October, and the 6 foot tall road markers stick out about a foot from the snow cover. You're going to be out there in a canvas tent and if you're lucky, you'll have a pot bellied stove. But you might not. Or it might malfunction. You're not going to be seeing the inside off a bathroom (or even latrine) for the duration (usually about 2 weeks, but sometimes 3). Fortunately, it's the 80s, so you still have a steel pot (helmet) that you can use for a wash basin....in REALLY cold water.
anyone who thinks these conditions are even REMOTELY conducive to s*e*x*ing it up with the boys: average daily high temps of about 20 below (F), no bath for the next two weeks...is clearly smoking the GOOD stuff and should be sharing, not accusing you of harlotry. Even the momentary advantage of sharing body heat is overcome and surpassed by the ewwwwww of making the showerless conditions worse.
My usual response was an eyeroll and, "Lady, not even on a BET..." Whether they believed me or not? I dunno. But it wasn't worth the effort of working that hard for.
