I have been hesitating about posting a report on Santo Domingo as the Gay scene there has deteriorated over many years. Once, there were many bars and an all-night disco loaded with handsome, available hustlers.
Sadly, that is mostly gone. The bars are, for the most part, gone, the disco closed, but the hustlers are still there for the looking.
I have been going there for much longer than I have to Thailand. I first went to the LOS in the early 80's - I was a figure in Santo Domingo a decade earlier.
Today there is a small bar called Friends, filled with hustlers ( locally known as bugerones ), a bar called Esedeku ( high class no known hustlers but never underestimate the Latin openness to bisexual advances), and one called Fagoo.
The area with activity is the Colonial Zone. There is a pedestrian street called El Conde which, where it meets with the Independence park is a cafe called Paco's. Sit there and you may well be found. It really isn't hard. You might even be approached by a fixer.
I now use Airbnb which is very affordable in the Zona Colonial. But, in the past I used a series of hotels all of whom take the ID card at reception and hold it until your guest leaves.
It isn't Thailand but, then, it's 90 minutes from Fort Lauderdale or Miami. I live in a heavily Spanish culture in South Florida so Santo Domingo is very comfortable for me.
I miss the old days but use a series of friends. By 'friends" I mean old hustlers who fix me up with new ones. I'm never alone. There is even a Gay massage place, very discreet no outside signage, that has been there for years called Juan Bin Bin - you can search for it. I even follow their posts on Instagram.
Frankly, it's a beautiful island with terrific beaches and a lovely colonial area. Surprisingly the largest tourist groups are Italians and Germans. They constitute a huge portion of the straight sex tourism area - loads of little hotel catering to the Italian men who come. The upshot is great Italian food. The Germans are at the beach area of Boca Chica. The two groups don't seem to mix. This is a really good restaurant city and I always look forward to my dinners there.
As I said, "not Thailand" Not even close. But, it may be where Thailand is headed.
I almost forgot to mention that the Lido theater is still open, straight porn and guys who want to be sucked - afew bucks to enter - no aircon so it can get terrible but if this is your thing it is, reportedly, heaven.
