The walls were always covered with graffiti, often accompanied by drawings of huge male genitalia, all about men seeking cocks to suck and other disgusting stuff like that. Worst of all for me was if I had to use a cubicle for a 'sit down jog', as my mother used to call them. And if anyone actually spoked to me, or even LOOKED at me, in a public toilet, my heart would start beating faster and my palms would break out in sweat. So, I always assumed the worst, even when I was grown to manhood myself. I guess it all stemmed from my mother's warnings about men who were 'dirty', as she called them, men who would do bad things to boys if they could. For example, I found it impossible to stand next to another man in a crowded urinal in case, well, in case.
From as long ago as I can remember, I have been nervous about using public toilets.
