I thought I'd do a quick and dirty survey of the adult internet sites. Theory Corner covered this a few years ago but the net's changed since then and it might be interesting to see how things are different now.
I'll start with a category I'm already familiar with...the one devoted to hairy nerd girls. I'm fond of this category myself but don't ask me to explain why....we're all play things of the gods. Anyway, this group hasn't changed much.
Here's a category I'm not familiar with, but I'll give it a shot. It's about girls flicking cigarette ashes on guys' heads. This girl (above) is remarkably friendly, a clear departure from the tradition that says only mean girls should play this role. I know I'll appear like a prude, but I admit to being disturbed to see a venerable tradition of meaness set aside like this.
This (above) is from a foot site that specializes in dirty feet. Yes, there is such a thing, and maybe that's new. Are those ants on the girl's feet? YUCK!!!!
I can''t explain why that is, it just is.
Men are hard to understand.
