kinda weird, but I have a similar story. I had to get an ultrasound done on my nuts one time and OF COARSE they send in this HOT woman to do it (not sure if she was a nurse or not). so it was a dark room and just me and her rubbing on my junk with jell and cupping them in her hands. not getting a boner was one of the hardest things to do in my life.
the ultrasound came back normal by the way.
but the nurse had herself committed.
