The reality TV star`s mum Kris Jenner is so keen for her daughter and husband Lamar Odom to start a family she has even advised her to try different positions in the bedroom to help the baby making process. Khloe said: "My family would love me to have a baby, but my mum is completely obsessed. "Once, she asked my assistant to find out when I was ovulating. Mom had her call my gynaecologist and then told me to plan a time to have sex with my husband. "Mom calls me all the time with different sex positions to try, she`s crazy. I have to keep reminding her that I`m her daughter, not a girlfriend." Despite Kris` tips and advice, the 26-year-old socialite insists she and basketball player Lamar are not making any extra efforts to start a family because she doesn`t think planning sex is very romantic. She added to Reveal magazine: "We do want kids but we`ve only been married for 18 months. We`re not doing anything to not have a baby, but planned sex is not sexy. We don`t do that."
