This is a true story- I didn't make this up.
A young man went to one of my colleagues complaining of erectile dysfunction. Apparently, he was wanting to get a prescription for the little blue pill and testosterone.
He was going on about his total inability to get an erection, whether it was stimulated or physiologic (morning erections).
After the history taking came the exan. By my colleague, a dainty blonde young woman. At which time, he spontaneously sprouted a huge erection.
Needless to say, he didn't get the medication. And my colleague left the room a dark shade of red.
