In her new memoir The Secrets of My Life, Caitlyn Jenner got a little too candid about her sex life with ex-wife Kris Jenner (back when she identified as Bruce).

“We fall in love quickly (we marry after seven months),” Caitlyn wrote in an excerpt published by People magazine. “Since — let’s not kid ourselves — everyone wants to know, Kris and I have good and frequent sex at the beginning.”

She continued: “I tell Kris about my gender issues before I make love to her. This will always be a subject of dispute between us. She insists that she was taken by surprise by my ultimate transition to Caitlyn, which obviously means in her mind that she did not know enough.”

Caitlyn said she dressed like a woman on a number of occasions in front of Kris while they were together. She even admitted to taking some of Kris’s makeup and clothes.

“I have bought makeup how-to books,” Caitlyn added. “I keep the books, along with my meager collection of clothing, in a small closet with a lock in the back of my closet. Kris and I have negotiated this, since she is terrified, as I am, of the kids finding something.”
