Cultural traditions limit them
Cultural traditions are deeply rooted in the hearts of Asian women. They are getting used to obey their own husband and be a good wife and a great mother. Once they get married, the only one they are loyal to is their husband, especially in sex. Asian women are only allowed to have sex with one man or their own husbands. Once they are found cheated on her husband, she will get punished. In the past, if a woman was found had sex with other man, she would be expelled from the family or divorce with her husband, even worse, some women maybe have abuse or humiliation. She would be seen as the greatest disgrace. Therefore, most Asian women don't have any interest to have a three way date or accept a three way invitation.
Network is disconnected
Because of state restrictions, the network is disconnected. It is difficult to find a way to connect with others who are from other countries. Some Asian women are open to sex experience want to find some threesome dating sites to have a three way dating, while, because of the network, they are unable to connect with foreign dating websites or other communication platforms. Even though they are willing to try threesome, they can only use the internal network. Under this situation, males who live in other countries are hard to get in touch with Asian women. They can change the network.
It's hard to break language barrier
Regardless of the network and traditions, language is another problem. Although English is the most spoken language in the world. A growing number of people have been learning English, most Asian women can't communicate with foreigners who are English speakers. It is because most Asian women have no chance to learn English and let alone talk with foreign people. When some threesome finder go to Asian countries, they find it is hard to find a third partner, because most women don't know how to speak English.
As you can see, there are three main reasons why it is difficult to find Asian women to have threesome. While, as people progress, the language barrier is slowly disappearing. More and more people know how to speak English, so you will have the chance to find an Asian woman to experience three way.
