Here are a few suggestions that you could consider:
1. Communication: The first step is to communicate with your wife and discuss what each of you are interested in trying. Be open and honest with each other about your desires and boundaries. This will help you both understand each other's needs and preferences.
2. Role-playing: You could try role-playing where you both take on different characters and act out a scenario. This could be a fun and exciting way to spice things up in the bedroom.
3. Experiment with different positions: Try out different sexual positions that you and your wife haven't tried before. You could also try using sex toys or props to enhance your sexual experience.
4. Explore your fantasies: Discuss your sexual fantasies with your wife and explore them together. It's important to remember to always respect each other's boundaries and only try things that you are both comfortable with.
5. Take a break: Sometimes taking a break from sex can help reignite the passion between you and your partner. This could mean taking a break for a few days or weeks to focus on other aspects of your relationship.
