You can do that by telling her you love her. Take her out to dinner and send flowers to her.
Ask her. Every woman is different. What turns me on might not turn her on. She won't mind you asking. She'll probably be grateful.
It depends like how long have you been her husband if you've been married for five years then you should know but if you're just married well maybe tell her you love her, go and do stuff that she likes, and do that night time stuff! Good luck!
