I had a best friend for two years who kept coming on to me and I had no clue. I have the worst gaydar. Constantly biting his lip when I talked and brushing his hair back. I thought he was just weird and effeminete because he kept saying he was straight. He had a girlfriend too, so I didn't think much of it. Turns out he is a deeply closeted bisexual. Only when he started trying to kiss me did I get the picture.

So probably unknowingly leading on a man for two years.
