Is it normal for my girlfriend to enjoy her skirt blowing up?

My girlfriend told me a confession, that she has a secret fetish, she gets pleasure out of the wind blowing up her skirt. She says it's like someone touching her.
She told me that when she was younger she would go to a field and lie down and let the wind blow under her skirt to lift it, exposing her panties, now she does it for me, when ever it's windy she wears a light skirt, pleated or wide, and tries to get the wind to lift it, I like it but is it normal for her to get pleasure from it too?
