Building off of maintaining desire in a long-term relationship, consider the importance of emotional attraction.
When you are emotionally attracted to your partner, you value them for more than just their physical appearance. Perhaps it’s sexy that your partner can carry out an intellectual conversation, talk about a novel, or discuss the news. This kind of attraction goes deeper than the physical. You desire your partner’s heart and mind and value them for who they are and what they stand for. While you may be sexually attracted to your partner’s physical appearance, developing deeper emotional attraction will make these feelings much stronger.
