Its only happened to me once. Had the hangover horn (possibly still pissed) & booked an expensive touring girl. The meet consisted of me blowing my load in minutes & listening to her talk about herself for what felt like hours while I struggled to get off the bed as I was such in poor shape. My fault for being an idiot & blowing smoke up her arse as I didn't have much to say apart from insincere compliments. Got a text a couple of years later which was ignored. Simply a case of easy money for her.
Could have been a lot worse if you had Brewer's Droop.
