Depressed, unemployed, down on my luck I responded to an ad for gay porn models (I'm straight). Guy was old and fat, nice enough guy, nice condo. I'm on a masage table and he's rubbing me up and down, flips me and over and starts blowing me. I'm not hard in the least, I can still remember how prickly his mustache and beard felt and wondered , "How do women put up with this shit?" So it's super awkward that I can't get hard, I ask if I can watch some porn and try to get it up. We try that for what felt like an eternity but no dice, I'm really desperate for this money ($300 fyi) so I ask if I can just give him a bj. He removes his pants and I get on my knees, before I can do anything I almost throw up in my own mouth and quickly tell him I can't do this, hurriedly and awkwardly dress and get the hell outta there.

Probably the most shameful experience of my entire life and was in the period of time that I would consider my rock bottom. Thankfully I've bounced back from those days and I'm doing fairly well now.
