Runciter I know there are providers that offer BBFS in those countries. I've seen a few listing that state its an option, but that isn't what I am in to or actively pursue. I feel the prevalence may be similar to here.
Each county definitely has their unique hurdles. For example, many Japanese shops just do not except foreigners (but it is slowly changing). The opposite is true in Thailand, where some shops cater exclusively to foreigners and do not accept locals. The laws and the lawlessness of mongering is very interesting. In Japan, it is illegal for the shop to advertise vaginal intercourse, but they can advertise greek. Yeah.. that blew my mind. Vaginal sex would be an option / add on you would talk directly with the provider. But it is included at Soaplands.
Before visiting these countries, I would suggest mongers do their research. Best to understand the way system work in various country. This help set expectation and avoid getting into trouble with the law or locals.
Would love to share my experience and adventures, but I do not think SA is the proper forum. SA is trying to run their site and cater to people looking for fun locally. This is a good place, and I want to respect that.
If anyone has the opportunity to monger in Asia, I would highly recommend it. I am sad, because I am totally spoiled now.
