Is it normal to be led around?

Is it normal to be led around by a dog collar and leash attached to my cock and balls? Happened to me once in an out-of-the-way men's room in a large mall. i admit i was horny. it was empty, so i entered a stall, took off all my clothes, sat down, and began to diddle my dick. a man came in, peed, and peeked into my stall. i continued to play with myself. he told me to open the door. i did and he stepped in and pulled out his hardening cock, and told me to suck it. (this was pre-AIDS) he told me to lick his balls. he was clean, and i enjoyed it, and my little dick was hard. he pulled out of my mouth and told me to wait, not to move, and he'd be back in a half-hour. i was sure he wasn't going to return, but decided to wait just in case. sure enough, he came back, and when i opened my stall door, he told me to stand up. he was carrying a dog leash and collar which he tightened around my scrotum, then yanked hard and pulled me out of the stall. i'm stark naked in the middle of the men's room. i asked him what he was going to do. he told me to shut up, drop to my knees and suck his cock. i was incredibly excited but too nervous to be hard. i sucked him for about five minutes, then he pulled out of my mouth again, and yanked me into the long hallway outside the men's room. it was deserted! he walked me up and down that hallway three times! if anyone turned into it i was a goner! no one did, and he took me back into the men's room. he was dripping pre-cum, a natural lubricant, and he fucked me standing up in the middle of the men's room. i'd never been fucked in that position before, and by that time i didn't care who might've walked in. when he came, i came without touching myself. he gave me the dog collar and leash, and i have it to this day, and often jerk off with it on.
