Motley Crue had group sex because sleeping with groupies got "boring".
The heavy rockers - Vince Neil, Nikki Sixx, Tommy Lee and Mick Mars - are renowned for their wild behaviour and when they tired of having sex with one fan at a time, they started "changing it up" and stepping up their antics.
Drummer Tommy Lee - who was previously married to actress Pamela Anderson - exclusively told BANG Showbiz: "At some point we got really bored [of the sex] and go 'how about two or three of them' and you just start changing it up to make it exciting. We'd run around naked at the hotel get hookers, groupies. Sticking things in their orifices, ordering room services."
The 52-year-old rocker explained people who think this is "wild" have no idea because doing the "same thing" constantly was so "boring" they'd have to take think of filthier ways to feed their overactive libidos.
He added: "We would do anything to break the monotony. People think it's wild but the same thing over and over again becomes boring. We would have to keep recreating."
