For me this is a golden age of submissives. You can find many pros on BP, Eros, and even CL, where you can also find some non-pros. It's a little harder to find them here on TER because many of the new review summaries say S&M, but then the review details say "don't know" next to S&M in the services offered category and the reviews don't mention any S&M activity, which can be frustrating. But try various search options here anyway. You might also want to post your request on the BDSM discussion board here. Good luck.
