1. To build a strong relationship, couples must make quality eye contact, focus on fun activities together like trying new hobbies or restaurants, and find ways to stay physically intimate through non-sexual touching like holding hands. 2. Good communication is also important for a strong relationship. Partners should be clear about needs and listen for non-verbal cues, and tune in fully when listening to each other. 3. Physical closeness through touch releases oxytocin and helps bonding, so setting aside regular couple time is important even with busy schedules. Simple gestures like hand-holding can keep intimacy alive along with sex.
