Not something that HE wrote, but that was written ABOUT him, a story I've posted here before.
He was featured in the Living section of a newspaper. It showed photos of the house he renovated with his own hands, the all-white first floor, even the furniture, and the Victorian bedrooms on the second. The crystal chandeliers in every room that he acquired from NYC antique stores, the several gardens that surrounded the house. A 39-year-old bachelor who never married, now retired from a NYC acting career and returned to his rural home town,1500 miles from Manhattan, where no man made is single past 25. Plus there was a photo of him, with a classic gay face.
My gaydar went off the scale. So I mailed him a letter requesting a tour of his place, the article providing his name and address. I was surprised he lived on the same street as me, and more surprised I'd never noticed his house.
He phoned me at my university office a few days later, his completely gay voice confirming my gaydar, and we arranged a meeting for me to see his house after I left the campus. We had sex in one of his Victorian bedrooms that first night we met, I moved in with him some months later, and we were together nearly 2 years.
My gaydar works with printed words & photos as well as in person.
