....I am interested in getting into punting so am using this as a stepping stone. She seems to offer more that just rub and a tug so thought I will try this out, build up some confidence and then go for a FS.
If you don't feel confident, I suggest you use a site like Adultwork which offers feedback, so you will know who is genuine and who is not. Have you tried the saunas themselves?
TBH, the likes of vivastreet, backpage etc tend to be a bit ropey.
As most of us will testify, it is a hit'n'miss thing until you aqcuire your own sense of what is hot and what is not!
Good luck...and never fear to ask here.
