I found this one from “Stuff you should know” very interesting. This is the video version of their podcast.

If you want to listen to it without watching, you can find the mp3 available for listening or downloading at https://www.stuffyoushouldknow.com/podcasts/nude-beaches.htm
I find that these two people approach the subject in a decent manner (forgive them their usual banter, it’s in jest). You may benefit from it; they hand some things to explain nudism to your unenlightened friends!
