To ensure a healthy and satisfying sex life in a long-term relationship, it's important to explore new sexual experiences together, such as trying different sex positions, introducing sex toys, watching pornography, or engaging in role-playing. Communication about desires, fantasies, and boundaries is crucial. Additionally, incorporating variety and spontaneity into sexual activities can help keep the spark alive.
