Pictures A new survey asked 2,000 Americans questions about their sex life including the riskiest locations they've had sex in. 58% of participants said having sex somewhere other than a bed made them happier in their relationship, and 70% said that having sex in an adventurous location made them feel closer to their partner. Couples have had sex on a moving roller coaster, the top of the Eiffel Tower, their boss's desk, inside a haunted-house, and many more.
