I had an experience much like what Crookedspin describes. I have found probably almost everything there is to find about my T online. She knows and does not care a bit. She thinks that I do things for a reason and she is often curious about why I do them, but she doesn't think I'm a creepy stalker (even when I feel like one). I think it helps to separate thoughts from actions. If you aren't going to do anything illegal or threatening with the information, then you really haven't crossed any lines.
