@Thebuddhist - Great story! This reminds me of how I'd communicate my thong wearing practice to past partners of mine. In the beginning I wasn't a full time thonger either - it was just something I did once in a while. So, I suppose, because of that my past girlfriends wouldn't know until sometime after the relationship had already started. I recall one night deciding it was time to tell one of these past girlfriends about my thong underwear. So, before we had our date night I put on one of my string thongs under my jeans. I'll never forget the surprise on her face when I took off my pants! She crawled up to me on all fours looking me straight in the eye with a rather engaging look - as she got closer she said, "What? Is that?!?!!" That was the best!
As I got older I made more of a point of bringing up this little fact about me much earlier to get it out of the way and keep it simple. I mean, if a guy wearing thong underwear made for men is a deal breaker then it's best to get that out of the way as soon as possible. But, I never met a woman that outright put an end to our dating over my underwear choice. (I can't say I ever understood this, but it was always the gambling, drinking, smoking and womanizing that put an end to my past relationships - but, it was never because I wore thong underwear - okay, that's a joke. haha)
I have told one or two colleagues of mine - but they probably thought I was cracking an odd joke. Interestingly, one of my colleagues, who I hadn't disclosed this information to, came out as a cross dresser to his entire family and co-workers. I knew him from work - going back 20 years. That seriously blew my mind - so then I told him I loved wearing man-thongs. Interestingly, thongs of any type aren't his thing.
Who would have thought?
