The most interesting change thru all the seasons
I found it interesting how when the show first started, the women always had full pubic hair and as the seasons progressed, the norm became what is known as the Brazilian or just a thin "landing strip".
I feel as tho the show was intended for women and if so, the mistake made was little to zero male nudity. Not sure why that was however.
I think the first 2 to 3 seasons were the best. After that, they kind of got both monotonous and too far out there to just be simple soft porn.
