I have no problems with tattooes personally. But I hate it when women hide or airbrush their tattooes and pose as to not having any in ads. I think for that reason alone providers know it can be a make or break thing. Hard to go to an elegant engagement with a dragon on your back, and a name on your ankle.
I think the reality of it is most hobbyist are 45 and older. So I figure more times than usually that group isnt as open to ladies with tattooes. It wasnt more universally accepted then.
I'm in my late twenties, sometimes ladies with excessive or large tats attract to much attention, and compromise discreetness. It matters not to me, but any provider with tats should knows this as honest truth.
