The Unlikely Mommy

Well, folks, here's something you won't believe! I'm a 52-year-old college professor, and recently, my girlfriend of five years turned to me one day and said, 'Teach me like you teach your students!' She meant it in a very specific way, the Daddy/Daddy's Girl dynamic. We started role-playing, and let’s just say, being her academic guide has taken on a whole new meaning! I'm loving it but also wondering if this is normal adult behavior or if I should be concerned. What do you think? Has anyone else here done something similar with their partner?
