When you’re in a long-term relationship, you might have sex for a variety of reasons: because you need to relax after a stressful day at work, because your partner did something inadvertently sexy while unloading the dishwasher, or — hey — because it’s Tuesday and you’re in the mood. There doesn’t always have to be a specific reason why you want to crawl into bed with bae, but experts agree that having a healthy sex life is an important factor within a happy, fulfilling relationship. And not just because of the potential of orgasms at the finish line: Turns out, getting physically intimate can boost emotional intimacy , too.But all too often, people in LTRs stop prioritising sex, which can affect other parts of the relationship as well.
