Check your local paper?
When I first started my business I advertised in the local papers and got all legit clients (males/females). Sure, I had a few ask when they rang me...but when I made it clear that it was all above board and no nudity...I never had a problem at all! Must of been in the way you worded it!
Deep tissue massage, for tired and aching muscles. Strickly therapeutic. (non-sexual)
That was how I was working my adds towards the end. Did it work, nope.
