Three couples who married as strangers open up to sexologist Dr. Logan Levkoff, talking about sex and intimacy, both key components of a happy marriage. Some couples are struggling more than others in this area. Can Dr. Levkoff help guide the couples toward a healthy intimate relationship?

Five weeks into married life and the three couples are a week away from deciding if they want to stay married or get a divorce. Spiritual advisor, Greg Epstein, encourages the couples to work hard on their relationship, and with the experiment drawing close to an end, this could be just the beginning of their marriages.
