You have hit the nail on the head - at least as far as those in our age range are concerned - "I have changed". We all change over time. I could no more be the sort of sex tourist that I once was than turn into a money boy! I do hanker after the old days in Thailand because they were so exciting and such fun. Whilst I still enjoy seeing cute young Thai guys, I now prefer their company over a drink or two. Besides, I have had the luxury and enormous privilege of spending most of my career in this exciting part of the world. I cannot imagine what life would have been like without being exposed early on to the cultures and societies of so many fascinating countries at a time they were each emerging in their own ways from the rigours of disastrous wars.
Unlike you, I have been based exclusively in various Asian countries which I have got to know well, including sexually. Like you, I have travelled the world for business very regularly but I have rarely had sex anywhere other than in Asia. Only in Sydney did have I had great times - and that's because I was always with Asians! I guess I am just the typical rice-queen!
As regular posters will know, my other Asian favourites - countries as well as their young men - are Japan and Taiwan. I discovered Japan within a few years of arriving in Asia and my first true love here was Japanese. Having since then lived there, returning many times has been a special joy. More recently I feel especially at home in Taiwan to the point where I would happily move to retire in Taipei if I had the funds to do so.
So I now have no personal interest in what happens to Soi Twilight. I am just thrilled I was around when it was starting up and during its long heyday. It sure was fun!
