I have always found the idea of sexual activity in a public toilet to be utterly repellent. Each to his own of course, but you won't ever catch me playing that game.
However, in more agreeable surroundings, some aspects of the ritual have a practical appeal. As we all have seen, Asian guys show their age in their faces long before their bodies. A fit Thai guy who is 35 years old might look positively ancient facially, whilst his lunchbox might be little changed since he was eighteen.
There is also the uniquely gay habit of having sexual contact with other guys without a word being spoken between them - something I am no stranger to..
Imagine, if you will, a gay bar, to the rear of which is a door leading to a dark corridor. Along the corridor are curtained cubicles on each side. Each cubicle has a stool and at the back of each cubicle is a round hole, maybe 40cm in diameter. At each hole stands a guy, either nude or in briefs, with his lunchbox centred on the hole. The customer chooses a lunchbox to enjoy, sits on the stool, draws the curtain behind him to afford some privacy, and after passing up an agreed fee, fills his face with dick.
The customer doesn't need to know the guy he's sucking is pushing forty and the guy doesn't need to know his dick is in the mouth of a fat slob - both can let fantasy fly away, to their mutual satisfaction..
- What's not to like..?
