Do guys care if a girl bites her nails?

I've always had this habit, I know it's terrible I just can't help it. I only do it when I'm nervous really or sometimes when I'm bored but I don't constantly do it. I don't do it in public either unless like in school when we have to give a presentation (I hate giving them) I'd be so nervous so while I'm sitting there hoping the teacher doesn't call on me next, I'd be biting my nails but that's about it. I am constantly washing my hands and I carry two hand sanitizers everywhere I go. Just wondering if it'd be a deal breaker.
