Addressing concerns about sexual performance or body image as a plus-size person involves open communication, self-confidence, and understanding. It's important to remember that everyone's body is unique, and there's no one-size-fits-all solution. Prioritize self-love and communicate openly with your partner about your feelings, desires, and any insecurities you might have. Remember that confidence can be attractive, and focusing on pleasure, emotional connection, and intimacy can help overcome any concerns you might have. If needed, consider seeking support from a therapist or counselor who specializes in body image or sexual health.
