Check out http://theartofdomination.com/ . On the Artists page, you might notice some familiar names, including some who post to TER on the discussion board -- even this thread -- , ad boards, and photo only board. You'll have to read each artist's description, but some are switches.

There is a sister site called https://theartofsubmission.com/artists/ . Some are subs only and some are switches who do both.

DISCLAIMER: I have no association with either place and receive no personal benefit from posting their info. Also, no one used thumb screws, nipple clips, or an electric cattle prod to get me to make this post. OTOH, no one used DFK, BBBJ, or other temptations to get me to post this, although I would gladly accept such bribes. This post for the benefit of the OP (and other readers) and was entirely voluntary and w/o remuneration of any sort.
