I also don't know where they go. Of the boys I was seeing 10 or 15 years ago, they're all gone.
Perhaps there's one exception, who I probably met around 10 years ago. He must be in his mid 30s, has a heavily photo shopped picture and is on ALL the apps.
I presume they've gone back home and got some kind of regular low paying job.
I know one who claimed to be set up and had purchased some land.
I remember another regular, who was showing his age, but was slim, good in bed, always willing to do long time and pleasant company to chat to. Then he moved his parents into Pattaya. He put on a lot of weight, was no longer prepared to do long time & the service wasn't as it was before. By my next trip, he'd just disappeared.
Of the more recent leavers, thanks to apps etc, I have a slightly better idea.
One has set up a business in Jomtien, well away from the gay bars, possibly with the aid of a sponsor.
One is in Yangon (I suspect he might eventually return)
One is back in Laos. Unlike many who do that, he's almost constantly on Grindr. I wish more would do that, as it takes longer to hire a Lao guy in Laos than in Pattaya.
