Did someone say SE Asia?
I taught in Bangkok for 6 months, Taught in South Korea for over 2 years.
Prostitution is very high in SE Asia. If you want to hook up with Asian girls hang out in areas where the college girls go to relax and party. Do not go the tourist areas because you are more than likely going to encounter prostitutes. Unless that's your thing. Remember, Aids and other sexual diseases are rampant. It's your life.
