Maybe I just have terrible gaydar, but I didn't know he was gay. I'm not surprised, but I didn't just assume it like I did for, say, Jonathan van Ness.
I liked Pee Wee's Playhouse as a child whenever I happened to catch it, but I never knew when it was on or followed it super closely. I had no sense of gay content at that age, though. Certainly I had no recollection of Tito - wow!
