A Teacher's Secret Pleasure

I've been in a long-term DDLG relationship with my submissive partner for two months now. We started off slowly, just exploring the dynamics and boundaries. One night, after a heated argument about classroom rules, ironic, I know, we ended up in a playful disciplinary scene at home. She got into character so well, it felt almost real...or maybe that's just me projecting my authority issues. Anyways, this isn't something I discuss with anyone outside our circle. But now I'm questioning if it’s healthy or normal for someone in my position to engage in such role-play. What do you think? Am I the only one?
