I listen to many podcasts on many different topics and have sought out kink podcasts over the years. Here's my reasonably comprehensive list.

Yes, there's Damiana Chi's, which is great, and I admire the whole new educational enterprise she is starting.

Masocast has long been one of the best SM podcasts, with a heavy focus on the New York scene. The host, Axe, is a lifestyle submissive married to a well known former pro domme. New episodes are very infrequent these days, but the library is rich. I particularly liked the episode way back with Yin Q.

As Mistress Ultra Violet mentioned on this thread, there is Authentically Kinky. The host, Jon, is a guy who has embraced kink in midlife, and he's very much surfing the good vibes, teaching kindness, speaking of "authentic selves" and the beauty of kink. It's a bit much for me and my darker soul, but he asks good questions and is so respectful of the dommes that they open up with good answers.

High-end pro domme Eva Oh has guested on many, many kink and sex podcasts, and she has her own, Teakink, which features stories from her life, spoken word essays, etc. The episode with her personal slave is a good one.

NY's Mistress Natalie doesn't have her own podcast, but she has guested on many, and she's fascinating, very open about her life, and very knowledgeable about kink. She lists all her appearances on her site.

If you google, you'll find a number of podcasts Mistress Isabella Sinclaire has done, and she's also had a fascinating life that she's very open about. Lucy Sweetkill is another domme who regularly guests on podcasts you can search for.

Off the Cuffs is a podcast hosted by a couple of lifestyle guys with various lifestyle guests. I don't listen to it regularly, and I rarely relate to its various subjects when I do, but it's definitely another take on things.

Your Kinky Friends is a webcast with various scene people, most of whom I've never heard of.

Viola Voltairine, a lifestyle domme who has written books about FLRs, has a podcast called Obedient Love , which is mostly her thoughts on gynarchy.

There's a good podcast called Good Pain that has a number of dommes and other people who deal with pain in some way. I recommend the episode with Olivia Troy.

Finally, there are a number of sex-related podcasts that discuss kink in specific episodes, too many to cite. On the Strictly Anonymous podcast search for the episodes with Ares, a guy who fell in love with a married pro domme, Raven. And episode 719 with Jay, who has seen many pro dommes and has an intense personal story. And on the Soft White Underbelly podcast look for interviews with Goddess Severa, Daddy An Li, Monique (fantastic episode) and several others.

EDIT: There are two more important ones I forgot. Like Your Kinky Friends and Soft White Underbelly, Danielle Blunt and La Maison du Rouge are YouTube channels. La Maison du Rouge is no longer active as its hosts, Lucy Sweetkill and Dia Dynasty, retired it, but all the old episodes are online and on-camera talks with many familiar dommes can be found there. Danielle Blunt's is ongoing, and her conversations range from very playful to quite intellectual.
