Are Thai sex dolls legal? As Thailand has a very conservative culture on the surface, it is difficult to give an exact answer to this question, but in many things it tends to be the opposite. For example, in Thailand, prostitution is technically illegal, but this does not prevent prostitution from taking place in broad daylight in the country’s major cities. We are not lawyers, this is definitely not proper legal advice, but anecdotally speaking, we have never seen any cases of sex dolls causing trouble to clients or importers. There is no worries about sex dolls for private use at home.
