Not Triggered By All Children? (POCD, I hope)

Okay, so as I've states many times, I'm scared of being sexually attracted to little girls. Again I must be specific, fair-skinned, blonde girls roughly around ages three to six.
Now, I understand OCD is usually very individualized, but I'm still a little freaked out by something related to that, which can be perfectly illustrated by something that happened today.

My mom and I were in Wal-Mart, and because the universe doesn't like me, there just so happened to be a little blonde girl with her mom(?) in the store as well. Now naturally, I got very nervous. However, when I got a decent look at her face, I calmed down because, well, her face wasn't the kind that triggers me... Does that make sense? But more importantly, does it still seem like I have OCD? I worried about this all the way home, and I'm very afraid because I know real p**ophiles tend to have preferences... Someone please tell me what you think.
