Donk: I really want to thank everyone for their input on this. And huge props to DMW for identifying "Mr. Airport Penis"! I'm probably being silly, but I know I will stress about this until I can communicate my apology to him.
Peter, it sure was a "shoe on the other foot" experience for me. "Humbling" might be a little strong (I'm just too damn cocky to be humble 8)) but it certainly was a new perspective. For the first time I know what it feels like to encounter a penis larger than mine. And I am both impressed and a little relieved that mine is not that big.
Re my "stalking" making him pee-shy, that surely was not the case. In our first encounter, HE came up to the urinals where I was in the middle of pissing and started staring at MY dick long before I had any idea of what he had in his pants. Then he whipped it out and stood there quite deliberately making it visible (and still eyeing mine the whole time). Then, within minutes after we left the first restroom, he headed into another restroom--with lots of guys coming in and out of it--obviously intending to put on another show. In our second encounter, it is true I followed him into the restroom. But he was already in there, had chosen a urinal right next to another guy, and had it out jiggling it, again obviously displaying it. (The other guy just pretended to ignore it. But he couldn't have missed it!) Meanwhile, Rip was obviously looking over the other guy's head down to where I was standing at the far end. (The other guy finished up and left before Rip and I were alone in the restroom and I started talking to him.) If Rip really just wanted to piss in peace, he could have gone into a stall and easily avoided the attention that his penis unavoidably gets.
As for future such encounters, I have learned my lesson. I will follow my natural instinct and keep my big mouth shut!
Re coincidences: I guess it is sort of strange that we would wind up on the same flight (especially since I was originally supposed to be on an earlier flight and changed my reservation). But I don't think it's such a huge coincidence that someone on this board knows him. Think about it--The internet has vast scope and this board attracts users from all over the country (and world) with a shared interest. A 14" penis is very rare. If a guy with a 14" penis makes a habit of showing it off everywhere he goes, it is going to get noticed. Not that surprising that it would have come to the attention of someone on this board.
Anyway, this is sure an experience I won't soon forget. Thanks again for all the input. |
