You're not a 16 year old pretending to be a virgin. You're a grown-assed woman. Unless you bust out some sex toys or take the dirty talk too far you shouldn't worry about any grown-assed man freaking out unless he himself is sexually prudish. My wife pretended to be much more sexy when we were dating than I found out she is married. If you can maintain your sexiness with one man over the years, you may just be the perfect woman.
Good luck in the real world and stay sexy.
