Yes, it does seem like humiliation has becoming more and more popular. I'm fine with it, because it's very fun. And while I'm sure that makes it slightly more time-consuming to sift through BDSM materials in order to find things you like... is that really so bad?

It seems like you've already found a compatible Mistress, and I can tell you that the overwhelming majority of pro-dommes will not include humiliation in the scene if you simply communicate that preference. I am considered a humiliation specialist but that doesn't mean all my scenes are heavy on humiliation, nor would I want them to be -- I'd get bored doing the exact same thing all the time. Humiliation clips are common because they tend to do well and POVs are very easy to make but you can certainly find appealing porn without even having to order a custom video, although that's also an option.

I guess I just don't understand your complaint?
