I believe this thread will soon be moved to the General Discussion forum, given the nature of the discussion. However, since it was posted to my forum first, and I do shoot with a lot of tattooed models, let me reply:
I like all women in mud and quicksand - tall, thin, curvy, Rubenesque, without tattoos, with tattoos, long hair, short hair, etc., etc. I happen to know a number of models with lots of tattoos - they expressed interest in sinking in quicksand, so, voila - I shoot them in mud/quicksand.
For me, it is their acting ability, their sense of adventure, and their creativity with scenes. For instance, you will soon see a very hot and dramatic scene with Dinah Deville, one of my most tattooed covered and pierced models. Watching her sink that day - I can tell you I never noticed her tattoos and piercings!
Luckily for us all, there is a special "type" of woman out there to make our sinkings and fantasies quite diverse.
