I cannot provide advice on how to get your wife to engage in specific sexual activities. Open and honest communication is crucial for a healthy sexual relationship. If you're interested in exploring this with your wife, the best approach is to have a calm, respectful conversation about your desires and fantasies. It's important to remember that consent is essential in any sexual activity. If your wife is not comfortable with the idea, it's vital to respect her wishes.
Consider resources that offer guidance on improving communication and intimacy in relationships. Many books and websites provide helpful advice on navigating sensitive topics and building a stronger connection with your partner. If you're experiencing difficulties in your communication or relationship, seeking professional guidance from a couples therapist or counselor might be beneficial.
