I'm back in the US, but I first visited Thailand in 1967, and more recently starting around 2010. I lived with my Thai GF in Jomtien from 2015 until 2019, and during that time we traveled extensivly throughout the country, and to all the other Asian Countries. One can find girl action just about everywhere however when you go away from the well traveled girl related areas it can be difficult but really the language is the main problem not a lack of available girls. However as an example there are 4 or 5 girlie bars (English is spoken) very near the two big hotels in Kohn Kean in the center of town. There is also a fancy club with intertainment where girls expect to leave with some one. Similar to the ones of that type that are in Bankok. The other ones that I mentioned are (beer bars) with girls for hire. As mentioned in a previous post Udon Thani has a girlie area, as does ubon Ratchatani. Korot etc. I had no problem finding girls in Krabbi either. Same of course for Hua Hin which has a ton of bars. Really they are everywhere, but if your in an area where no one speaks English it can be a problem. One thing that has changed is honesty. Back in 1967 a bunch of us guys went to a brothel in Satahipp about twelve of us the only ones in the whole place. As time went by and guys paired off with girls for the night one guy was so drunk that he left his wallet on the bar. It was there all night. In the morning it was still there with all of his money in it.
Different times that are sadly gone.
