Back when I was around 13~14 I got gifted half life 2 by a steam friend of mine, I immediately downloaded the game and started playing, I was having fun until I made it to kleiners lab. I looked at dr kleiner and started feeling things I'd never felt before, something about him, his bald head, his coat... I couldn't take it. I immediately got a boner and started stroking it a little bit, all while doctor kleiner was talking, I got to the point where it was too much, and I busted all over my monitor, right on dr kleiners bald slappy head, from that day on, every time my parents weren't home I would log onto my computer and furiously jork it to dr kleiner, I even got sfm and learned how to model so I could create him naked and make animations of him twerking... Eventually I realised how much of a problem it was and managed to stop with the help of a friend, but now everytime I play half life 2 I start blushing when I see dr kleiner.
