Khloe Kardashian is laying down the law for her next boyfriend … and if he’s not cool with plastic surgery, he’s not making the cut.

The reality star rattled off her dating demands during the latest episode of “The Kardashians” … telling Kim Kardashian her future man needs to be successful, have good teeth, and absolutely cannot have a “micro penis.”

“I’m no sugar mama,” Khloe declared … but that’s not all … Khloe said her next guy needs to be open to beauty treatments, or at least keep his mouth shut about hers.

And Kim summed it up perfectly … “Must be okay with plastic surgery,” to which Khloe replied, “Sure.”

The sisters were making the checklist as part of an assignment from Khloe’s therapist … and she also wants someone who’s supportive, family-oriented, and won’t cheat or lie.
