They say whenever you see a beautiful woman, there is a man somewhere who is tired of having sex with her. That’s what’s happening with Lindsay Lohan and Samantha Ronson..except it’s another woman that’s tired of having sex with the hot chick.

Word on the street is that Sam is not only worried that Lindsay is falling back into her party-girl ways, but their friends are also whispering that Lindsay is still very much into guys. Add this to the fact that Lindsay is all up Sam’s butt anytime she has a DJ gig and you’ve got very raw nerves over at casa LoRonson.

A source said: ‘Sam needs her space away from Lindsay and really needs to take a long look at what the future of this relationship can be.Clearly, they were spending a little too much time together, and Samantha was the one who said Lindsay was getting in the way, and even acting obsessive at times. If these two are going to be together for the long term, Lindsay is the one who’s going to have to change, calm down, and get real. Sam’s made that very clear to her.’

Word to you LiLo…get yourself right or you’ll be back to bouncing from Hollywood boy to Hollywood boy…
