This weekend I also told a couple of my friends.
One friend told a kink secret to us, he was super nervous andawkward about it and the other immediately chimed in revealing his own kink secret. Initially, I wasn't going to share, as my diaper time is largely solitary (my wife knows and doesn't care but doesn't want to be involved, which works for me) and had little relevance. The discussion continued, and it came to a point where I wanted to assure him that these secrets are things many people have, and in a return of the trust he showed in me I told him my side.
Obviously, it was met with "Oh, that's okay" from both friends. Honestly, I don't think I feel any better having told them as outside of me talking about it or them snooping through my closet they wouldn't have come into contact with it. I do hope though that my friends understand that I reciprocate the trust they have in me.
Though I'm merely a lurker 99% of the time, I do appreciate the large portion of this community that is very strict about not including unwitting public, be them strangers or friends in this fetish.
