Can you help me, please?

My girlfriend is the sweetest girl ever. She is 22, a "good girl" who goes to church a lot, loves kids, wants to be a teacher, and is just the sweetest thing ever. She always dresses classy and doesn't drink or party at all. Well, she knows I like to smoke cigars occasionally and drink a little bit. She told me the other day that even though she doesn't like smoking and wouldn't want to do it herself, she finds it very attractive when I smoke a cigar. When I'm dressed up and how I look manly doing it. Why would she tell me this?
