As far as I know, just my wife and a few ex-GF's. But I'm sure they all have told some of their friends about it, I really don't want to know who else knows.

Anyone who has seen me on the beach! This certainly includes peopleI know. On one occasion walking back from the sea in a minimal g string, my neighbour had set up close by. We had a normal chat while I towelled down. As ever secret is to act normally. I just don't draw attention to what I am wearing. I wear a J Snyder Kini for pool lap swimming - same applies. It ain't a secret!

Just spent the day on the beach with a woman friend. She got a phone call. She proceeded to tell the caller she was on the beach with me and I was wearing a thong. This is not new for me. She has the habit of telling everyone that I wear a thong, friends, strangers, acquaintances, and any one else she encounters. She says it with pride. As a result I’m sure there are a bunch of people that I never met that have been told of my swimwear choice.

My parents, sister, companion/friend. I don't need everyone to know. Except for the people who help me with laundry.

Was playing a drinking game with another couple and a question came up that I was able to make whoever I wanted to take a drink for the number of red items I was wearing. I had no red on but my buddies wife came out of no where with the question of what color my thong was. Im not sure if she was joking or knew I was actually wearing one. My wife laughed a little and pulled my waistband down and told them it was blue. They couldn't see because we were across the table at a picnic table. I asked my wife on the ride home from the vacation and she says she didnt tell her that I wear thongs and had no idea if she was just joking or if she knew. The thought of someone besides my wife knowing I wear thongs was a little embarrassing but at the same time very exciting in a way as well. I keep hoping that the topic comes up again in one way or another!

585, that's funny. Maybe she noticed through your shorts/pants due to the outline of the thong...

My parents, my sisters and brother, my exs, and anyone who's seen me at a beach I went to.
