t will be very difficult in a real life.
Kissing, hugging, holding, touching are good feeling that Gad gives to human being. But they are considered as bad maners for Thai culture. It's different for foreigner who is more natural than Thai.
I have a Thai friend who confirmed never hold hands with her English boy friends for five years before their wedding day. Now they have two kids. They have been married for 15 years.
So it depends on how much your bayfriend understand you from the beginning, and most of all how much he loves you !!
Come on give him a kiss !!!
