Pong, I'm not sure what sort of information you are trying to give. I have been to Santo Domingo over 120 times - I stopped counting a few years back. I was held up once - my own fault dead drunk after an art gallery opening. All I lost was some cash. Otherwise I have had no issues. Cuba is an option, not so easy for Americans as there are still many travel restrictions. Remember, however, while non commercial same sex relationships have been legal since 1979 - you will be paying. That makes it commercial, hotels do not accept cuban/tourist liasions. There is no wink and a nod. Some handsome, young tourists may report glowing sex - most readers of this board will not find it so easy.
As to flights - I get to Thailand on a connection. Don't most people? In my youth I often went to Europe on cheap Icelandic air flights connecting in Rekyavik to Luxembourg city. I have never asked the swarms of Italian tourists how they get there - but they do. I'm not their travel agent. Yes, there is a beach oriented tourist zone in the North of teh Island. Your point escapes me?
Finally, yes I'm aware that many Dominican women end up in Europe. As to your question about why the men don't do the same I must say - who knows and who cares?Since hetero sex tourism is vastly larger than homo it might explain the differences. But, again, I miss the point.
For me, and many others, this remains a lovely place to have a short vacation. Sex is readily available, the men are famously endowed, costs cheap., food good and hotels that give the "wink and nod" are plentiful.
The only caution I give is simple. Domincan men are ( as a result of brutal Haitian invasions ) laregely mulatto. If your type is Chinese/Thai you may not find your type. If you like the Issan type you might be more happy. My tastes are more catholic and I've been happy and always able to find the more pure Spanish looking among the youth. I hasten to add that this is simple sexual taste and I accuse no one of racism by saying they have a preference. I find that argument a poor one indeed.
