I'm in the early stages of building a new site with Divi. It seems to be much more robust than all the other themes I've tried this year. It's more difficult to learn than a lot of the out-of-box ones out there but I'm tired of trying out one new theme after another and having to constantly change because whatever the limitations. So, given it's flexibility, there's a chance it could be BDSM friendly. Whatever that means. Before that, I had been using Thesis 1.86 on pretty much all of my sites for the past few years.
