PetrPalooka, i don't know about being a mentor, but i do know that this site has ample amounts of information pertaining to what your looking for. I was able to find the goods by doing my research on this site. Just look for the places that are with in your price range and also have descriptions of girls you fancy. Then try it out. Also try the half hour first so you don't waste your money on a legit parlor. Whatever you do don't mention this site as the source for knowing about them. Instead say your friend told you about them.
Always make an effort to let the massage therapist know you are looking for something extra, without pushing to hard as they don't want feel like they are being pressured. If you have found the proper place that gives extras your advances will be well received.'
Good luck and keep on trying. Massage Parlor games are the most fun for me.
