I am also sorry that that happened to you. It is a very hard thing to get out of your mind, and I find that I "look" at the person differently (at least for a while) after I know they have been s*. I know its not their fault but, it freaks me out and makes me think differently for a while.

As time goes on the image thankfully gets more and more distant and distorted in my mind, and Im sure it will for you too =) In the mean time, the youtube/laughing thing is good medicine
