I’ve had experiences of walking into restaurants while traveling through and having girls take pictures of me. At the same time, the general culture is heavily based around reputation and some girls don’t want to be seen as Farang Hunters.
The best way to deal with these issues is by getting on a dating site.
There are plenty of features that can help you to communicate with your matches: live chat, video-chat, phone introduction and even sending flowers and gifts.
You'll need to buy credits in order to be able to use all those tools.
One downside is that there are very few Asian women living in UK registered on this site (a problem if you are searching an Asian partner in your own country).
