When I first got online about 9yrs ago, I used to chat to a local bloke on yahoo messenger. Met him in a UK chatroom.
He was really funny, witty and charming. Single and around my age.
I was quite green when it came to the internet, it was all totally new to me.
Anyway, one day I stumbled upon a photo album he had on his yahoo profile (don't think they have them anymore), so I took a look. I was soooooooooooo shocked, it was full of hundreds of pics of him abusing his cock and balls in different ways. Some where he had contraptions hanging off his balls with weights in, some where he had a bungee strap attached to a harness round his balls and the other end attached to a hook on the wall and his balls being pulled about a foot behind him.. etc etc.
I asked him about it, and he was really embarrassed, he didn't realise the album could be accessed by anyone without his permission.
Hilarious really - and me being me I was fascinated, and a little repulsed, by it. He was still a nice guy, the fact he liked to torture his own genitals didn't change that, but it kinda put me off meeting up with him. But on the plus side, it seriously opened my eyes to the internet.
For example, before that day CBT was something you had to do before you were allowed to take the L plates off your motor bike!
