Things in Miami were going so well for Scott Disick: he impressed girlfriend Kourtney Kardashian with his responsible behavior, he made a new best friend, and he finally got to live out his race car driver dreams. But something is still frustrating Lord Disick: His sex life.

Or, should we say, no sex life.

“We used to have sex all the time,” said sadface Scott on the latest episode of Kourtney and Kim Take Miami. Scott and Kourtney’s second child Penelope was born last July, and apparently things haven’t bounced back in the bedroom.

After Kourtney shoots down Scott’s request to go make out with him in a dressing room, Khloe agrees to go hang out with him, because they’re pals and because Kourtney really has been a bit of an all-around bummer so far this season.

Khloe wasn’t sure if it was because Scott is desperate for attention or what, but things got a little weird when these two were out shopping for what we can only assume are very expensive t-shirts. Not only did he compare his sex life with Kourtney to Khloe’s with husband Lamar Odom, he accidentally (we hope) brushed her boob with his hand.

“Scott doesn’t think there’s boundaries between me and him,” Khloe explained, and things only went downhill from there. First they went out for ice cream and he made gross jokes about Khloe being a “very sexual eater,” then he got drunk and touchy-feely when they were all out one night!

Khloe finally got pissed and brought it up at dinner, where Kourtney didn’t seem to care but Scott was sheepish. “I didn’t mean it offensively, and now I feel bad about it,” he said, which is good because Khloe laid down the law: “You’ve got to curb your enthusiasm because Lamar might assassinate you.”

You heard the lady, Scott! Let’s only get hands-y with our own girlfriend from now on.
