Tony Romo enjoys sex with Jessica Simpson, but doesn't see it going anywhere?

Although Jessica and Tony are very much still together (she threw him a 28th birthday party in Dallas on April 19), OK! reports that Tony and, in particular, his family, may not be loving the fact that Joe Simpson is constantly popping into the picture.

"His [Tony] family's view seems to be that Jess and her dad, Joe Simpson, are bringing Tony down," a source tells OK!. "I think they are ruining his image, as well as trying to capitalize on his fame, in order to boost hers."

The source also shared a revelation about the Mexico trip that Jessica and Tony took with his teammates in January, before the NFL playoffs. "Everybody agreed to tell no one about the trip," says the source. "On the day they were flying out, who shows up? Joe Simpson. Tony and the other guys thought it was weird."

"Tony says they are just friends with benefits," says the source. "The sex is good, but he doesn't see it going anywhere."
