Hey wanted to get some ideas about what to write about for my blog.

I already covered somethings I think are becoming more mainstream, though extreme.

Fisting (lots of girls on FTV doing it)
Anal Fisting (Everything Butt about every other video)
Forced Anal Prolapse (Seems like every new Evil Angel video has it now)

Anything else mainstream companies seem to be doing that were once considered to be very taboo, uncommon, or only certain niche sites were known for?

Thanks!
