The preference for having sex with the lights on or off often varies from person to person and can be influenced by factors such as comfort, intimacy, and mood. Some individuals may prefer the lights on as it allows for visual connection and enhances the experience by fostering a sense of openness and vulnerability. This can lead to increased intimacy and a stronger emotional bond between partners. On the other hand, some may choose to keep the lights off to create a more relaxed atmosphere, allowing them to feel less self-conscious and more focused on the sensations of the moment. Ultimately, the choice between lights on or off can enhance the overall experience, making it more enjoyable and fulfilling for both partners. Each preference has its own unique benefits that can contribute to a satisfying sexual experience.
