They aren’t making new ones anymore, but you might enjoy the back catalog of the “Black Box Down” podcast. I think it had about 12 seasons.

A couple of book recommendations for people worried about this kind of thing.

“Bonk” by Mary Roach. She’s a very good science communicator and is also quite funny. There’s a lot of good info in here.

“A Billion Wicked Thoughts: What the Internet Tells Us About Sexual Relationships” by Sai Gaddam and Ogi Ogas. This book is not rigorous science, but it is no total junk. It is also informative and entertaining. A tidbit of generalized info: men tend to think about dicks and look at dicks way more than women do.

Some of us have moved on from atheism to post-theism. In part, because some atheists can be very annoying. (Thanks a lot, four horsemen of the dorkalypse).

To your point, I do sometimes miss the music, rituals, fellowship, and liturgy of my old church. It was a mostly wholesome experience, and many of the people were very good people. In particular I miss being a member of the choir.

It was interesting (and revealing) when I left the church to experience which of my old friends from that church were very accepting of my walking away, and which ones wanted nothing to do with me anymore.

Anyway, I have found that my table top gaming groups (mostly RPG games) have helped a lot with social needs. Not a full replacement for a church, of course. But it is an activity that creates interpersonal bonds and encourages folks to be vulnerable around each other at times. And, a little bit like churches and temples, the quality of the experience can vary greatly from one group to another.
