Unlike his famous brothers, Jonas has remained largely out of the spotlight, save for a few appearances on Jonas L.A. and Camp Rock 2: The Final Jam. He also lent his voice to the anime film Ponyo on the Cliff by the Sea alongside Noah Cyrus.

Well, those Jonas boys have certainly grown up right before our eyes. Joe went full TMI on us about his sex life earlier this week, telling PrideSource that he's a fan of bringing "whips and leather" into the bedroom. See what he said, below.
