Is it normal that i can't stand getting dirty?

I hate getting dirty. I'm pretty much afraid of getting anything on my clothes. It doesn't matter what I'm wearing; new or old, white or black. If my clothes get dirty, I will freak out. I don't like doing anything that might get my clothes dirty. I hate doing gym outside because the gym teacher makes us do things that will get us dirty. We have to go outside when its muddy and we still have to do pushups and situps, which means laying in the mud and grass and getting it all over your clothes... gross. And he makes people dive in the mud during the rugby unit. I'm a pretty neat person, I never mess up my clothes. If there's a stain on my clothes, there's a 99.9% chance its from someone else. And if my clothes get dirty, I have to change and clean it immediately. So, am I normal? Please comment.
