Bareback with young ladies, massage, bars/booze, good golf nearby, inexpensive housing and food.
It is a dream for many who have been suffering and controlled by western thinking and disgusting women.
Up to you.
You will probably quickly get bored in Samui.
You say really nothing about any hobbies. Golf? Watching sports?
On the big picture if you are past partying, ladies and travel, life can get a little boring anywhere. Normal for many once you hit a certain age the excitement of life has mostly passed.
Just try to stay healthy and keep contact with your daughter.
