Personally I would be honest, so far every person that ive have had to spill the beans to has been cool with it.
One friend unexpectedly came over to bring me ice cream when i was not feeling well and I had my playpen set up, she asked and said i'm an ageplayer. " ok, cool" and that was the end of it, now she comes over for kids movies and stuffie snuggles when she is feeling down.
I send a photo of a creepy doll to friend from work, the playpen was in the background and she asked what goes in the playpen, I said I do.
Now she follows my little IG account.
Last month on the way out of work, a coworker asked if i was a little. I figured if she is asking she knows about ageplay, I said yes. She came out to me as a little as well
I have found honesty is the best policy but results may vary
