it's a good site
some of the girls are awesome, but some seem out of place.
most of the photograpy is excellent, photographers who actually understand scene composition, colour and erotica, unlike the "big names" Domai, Hegre, metart. SG is better than similar sites like gothicsluts as they are often a bit crude.
"Mary", I think is her name, is outstandingly beautiful, nude, semi nude, whatever.
On numerous photo-enabled forums, the SG threads are often the most popular.
good luck with that, whatever your intention.
