Lindsay Lohan: Sex Marathons and Addictive Personality

Those rehab romances can be tough to break! Lindsay Lohan's rehab boyfriend, arrestee Riley Giles, kisses and tells to British mag News of the World -- claiming Lindsay craved marathon sex with him.

"She'd demand sex again and again. We'd go at it for hours." Poor bastard.

Giles also says there were times when the two "didn't get out of bed for days."

The bigmouthed hump also says that LiLo has an "addictive personality," but he thinks she truly does want to stay off drugs.

He claims the two were in love, "Lindsay would tell me she loved me and I'd say that to her, too."

"Lindsay's definitely a nymphomaniac. She's wild in bed. We'd have sex a couple of times in the day and then go to it through the night.

We once did it four times in a row straight. That was crazy. Lindsay was insatiable. She'd demand sex again and again. We'd go at it for hours. She'd have worn out most guys.

I couldn't believe I was looking down at Lindsay Lohan naked. We'd barely gotten through the door when we just ripped each other's clothes off. Lindsay is so hot. She has a great body. Her backside is fantastic, perfect, all plump and round. She has great curves but her belly is nice and flat and toned. We couldn't get enough of each other."

Giles claims to still talk to Linds every day.

Not so sure about that after she reads this!
