Thailand- Any sites to recommend?

Hello fellow mongers.. I’m coming to you because you’ve never steered me wrong in the past. Do any of you have websites where I can learn more about the different red light districts in Thailand? My best friend is Thai and we are planning a trip for next year. We will be sight seeing and seeing his family, but also will be spending time in Bangkok and Pataya and would like to have some fun in their red light districts. I’ll be using reddit to learn as well but am looking for a Tuscl type site for Thailand.
