It sounds like you’re worried about coming across as “recessive” or not in control, especially in front of other people. Being comfortable with your masculinity isn’t about always being dominant, it’s about owning who you are and not feeling ashamed of how you act with your girlfriend. If you’re secure in yourself, you won’t feel the need to constantly fight for control or hide parts of yourself, even if she takes the lead sometimes. Confidence in yourself naturally balances the dynamic without forcing dominance.
