I'm new to this group, maybe the last in a while by looking at the postings.
My take on pubic hair and a few other things is this:
From what I have read, shaving or depilation has come and gone over the years but dates back to ancient times. The choice of shave, trim or grow wild is strictly personal. It is influenced by the styles of the times. It also varies from region to region. I don't really put much stock in the theory of shaving to look prepubescent. To let it grow is natural, but so is hair on the legs and armpits. You may think pubic hair is normal, but here in the U.S. you probably don't think the same of hairy legs and pits.
Personally, I lean towards shaved for models, but any style that the model is comfortable suits me. After all, the model is going to look and perform the best when they are comfortable with their own appearance.
On a similar note, what I don't care for is breast augmentation. It might look great when clothed, but nude, with few exceptions you can spot a mile away. Give me natural any day regardless of size!
Tattoos and piercings are fine for most work as long as within reason. Unless you are into body art, full sleeves, back and chest pieces just detract too much.
Let's add body type too. Personally I don't care for scrawny models (women in general for that matter).
Bottom line - it's what floats your boat.
