Only really been three people for me..
My first was with my ex. I had no idea. We never really spoke about it until one drunken/stoned night. Started with a dare. But didn’t really eventuate into much more then licking.
The next was a friend of mine I knew for years. We often spoke dirty together and sexting a lot. I brought the idea of having a dog lick me and it went from there. To the point where he went and bought a dog for us so we could play.
The latest was a guy who lives a few doors up from me. We had a conversation when he was walking his dogs. He started the idea and it’s been fun ever since.
I would never bring it up in a conversation. Just have to read people and see the signs. But must say it’s great to have this forum for local meetups and conversations. A safe space to be open about our desires.
