The connotation of "moist"

A student in my Shakespeare class announced that the word \"moist\" (which I had uttered to describe Egypt in Antony & Cleopatra) is offensive to women. Some of the other women in the class concurred (not hostilely--just as a matter of information for a clueless male professor). I was somewhat flabbergasted, and nobody would articulate a reason for the offensiveness--except for one male student's eventual suggestion that the word reminds women of s e x u a l arousal. That association is not at all beside-the-point of my description of Egypt in the play--but why would such a connotation make the word offensive per se? As far as I could ascertain, \"damp\" and \"wet\" don't carry whatever stigma attaches to \"moist.\" What am I missing here?!
