Kourtney Kardashian Talks Painful Post-Pregnancy Sex, Buying Lube (VIDEO)

Kourtney Kardashian talks with Kim about wanting a second child and the challenges in getting there in this clip from 'Keeping Up With the Kardashians.' Kourtney gave birth to son Mason last December.

When Kim asks if you have to wait six months after giving birth to have sex again, Kourtney replies, "Most people can have sex six weeks after, but the doctor told me to wait two months."

"Why?" Kim asks.

"I don't know, but once the doctor gave us the okay, we were like excited to try it, but it was very painful," Kourtney says. "It felt like a metal pole is literally ramming you in the crotch."

Kourtney also reveals that because she is breastfeeding, her estrogen is low and she's not "very juicy down there," but she is embarrassed to buy lube.
