I think there are "triggers" for us males who enjoy the RT scene, that make us think of the issue of rectal temperature taking. For me, as a male, I see many great looking females, and wonder what their experiences were or possibly are with RTs. Then too, the female next to me, bending over, in a pair of jeans that ride low, exposing a portion of that panty or thong she's wearing. As well, walking by a female who has her legs spread (not intentionally) and there's a great view up her skirt does it for me. Or the female(s) overheard discussing their last visit to their gynecologist or doctor, and in some cases as I've heard on at least two occasions, their stating in not so direct words, but alluding to their temperatures and the embarrassment of having had them taken, "that way!"
And hey, ladies, if you've had these experiences or whatever regarding males and what triggers you to think about their RTs, please chime in!
