"Relationship therapist Marissa Nelson believes so strongly in the healing power of vacation sex that she created an entire business around it: IntimacyMoons. Several years ago, Nelson noticed a recurring theme among many clients in troubled marriages. Some would take trips to mull whether to divorce or stay together; those who did go away to a hotel usually opted to remain married, raving about reconnecting via the great sex they’d enjoyed on the trip. In response, Nelson created her startup, which whisks a small group of couples away to the Crane hotel in Barbados for a few days. The vacation combines private couples’ therapy sessions with a chance for participants to unwind (rates start at $2,500 per couple)."
