Thai Girls on Online Dating Sites
The best way to hook up with Thai girls for free is by using the Online Dating Site like thousands of tourists and expats do every day. While the majority of them isn’t out for money but just fun, you do also find these so called Sideline Girls who are mostly university students that look for a source of income if they don’t have a “real” part time job or their parent’s funds are not sufficient to pay all the bills. Sideline girls are like Giks (mistress) with the difference that you pay them a fixed amount per month and can call them whenever you feel like.
- Prices: Negotiable and depending on the girl from 3,000 to 5,000 Baht a month, often more if she is white skinned and more than decent looking.

They provide very clear information about how everything works (you can even track them on a map to see where they are) and also provide great pictures of the ladies that are available.
- Prices: The typical prices for escorts are 5,000 Baht for 2 hours, 7,000 Baht for 4 hours, 9,000 Baht for 10 hours and 12,000 Baht for 24 hours. The standard additional charge for A-Level (anal) is 2,000 Baht.
