Your sex life with your longtime partner doesn't have to dry up and become nonexistent the longer you two are together. According to a new study published in the Journal of Personality and Social Psychology, couples who are attentive to each other still have good sex. Simple, right?

Responsiveness, which the study describes, is considered an intimacy-building behavior which makes your significant other feel more valuable and special—that then leads them to sexually desire you more.

"Engage in mutual conversation and listen with an open mind—really listen, without interrupting or pre-judging or showing off," says lead study author Gurit E. Birnbaum, PhD. So essentially, if you're looking to keep the romance alive in the bedroom with your partner, all you have to really do is listen to them and give them the emotional response they ask for.

Something easy to try to do is keep up with the text messages that your partner sends. Never let them go unanswered. If they feel like you're too busy for them, they will definitely not feel appreciated.
