In some sense, I can appreciate sites like Little April or Meat Holes or non-consensual fantasy sites. (So long as the women know what they're getting into before hand, and are paid well.) I think it is important to have legal porn featuring consenting adults that pushes boundaries, because it's very much a free speech issue.
But, aside from philosophy, like Meat Holes and Little April, I don't think they make the collective "us" look good, and it's not the sort of thing I would want to promote. I have never believed that what is legal (or Visa-approved) dictates morality, so saying "hey, Visa's okay with it" is just an inane sig-post answer to an ethical debate.
I think lots of sites play on the elements of consent and coercion. (How how drunk girl sites? Or the whole theme of "this dumb college girl desperately needed money to pay her bills, so she agreed to suck my dick for cash"?) For example, what's the real difference between Sleep Assault's issue of consent and that on
http://www.herfirstdp.com ? Quotes:
"It didn't take much convincing to get Lizzie to agree to fuck us, but she didn't realize that she was going to be our next DP conquest!! She wanted it slow at first but once she felt both rods drilling her at the same time she begged for it hard and fast!!"
"Women like to act like they don't like sex. Chrissy was no different. She had a bite like an alligator but as soon as we started talking her language -taking two cocks- she let down her guard. We had her screaming like an alley cat by the time we got done with her!"
You could argue that the Her First DP is saying that if you start doing something a woman doesn't want, she'll fuss a bit, but then be begging for more. I'm not trying to pick only on them, it's just that they also advertise here, and I've never seen any comments about their ethics.
I wanted to add after MadMax's post that I'm not trying to be a crusader for "vanilla" porn. My personal issue with these sites is not about "Do some women like to be sleep-fucked?" or "Are some women really submissives?", it's a matter of how the content is framed and pushed to the surfer. For example, one of my boys is the only guy who I'll be submissive with. We sometimes get into hair-pulling, rough behavior, "fantasy force", etc. But, if we shot photos of it, and put text with it saying that I was being raped, I wouldn't want that on my site. I'm not being raped, I'm with a very trusted partner, and I can say no at any time. (As all good kinky play goes.) When you remove the "real life boring details" of consent, trust, and personal preference, I think that's when it gets iffy in my book.
As my fellow bleeding lady Trixie said, maybe sites should post warnings, talk about BDSM rules, and have some form of responsibility to the surfer's sexual education. Yes, people do look to porn to see what to do and how to do it, for better or worse.
