LOL what about it?
Broadly, I guess just that I've done a lot it, with a good number of partners. Like, almost always as a sub, except for the odd scene here or there where I've topped either at their request (like a service top) or because I wanted to teach them something (as in, teach someone who wants to Domme by showing her in the form of having her sub to me and doing whatever it is she was curious about.) or just for the lulz/general sexual exploration (Actually am planning one for next week with Ms.G

). Oh, and lots of scenes where there's been more than 2 people and I was subbing to one but topping the other along with her.
Rope work, restraints, canes, crops, whips, open hand strikes (like face, and the obvious palm of the hand spanking) water sports Sensation stuff like pin wheels, ice, blah. A few forays with electricity, I've administered water-boarding before in a kink context (Have only had it done me in the context of a S.E.R.E. course) and of course the softer stuff that overlaps with more or less regular sex like "forced" nomming of vagoo/pooper (not that it really requires any coercion to get me to do that) otherwise kissing/licking/sucking body parts (fingers, toes, nipples, whatever...again, its something that really falls into regular sex, at least for me) plugs/strap ons/etc, tease and denial, choking, blindfolds.
again, if you have a particular question about any of that, ask away or PM me.
