hey Graf your problem is you didn't read through this forum before you posted. This is a true ex-pats forum not a sex-pats forum!!
And to answer your questions you are not going to get cheap sex from Thai girls in Udon. Why because most the girls live around here and will not want to be seen by family or family friends plying that sort of trade. That's probably why you will find a lot of those type of girls in Bangkok or Pattaya away from view of their families because ignorance is bliss
