S4·E9 I Want Your Sex

Khloé makes a "love tape" for husband Lamar Odom while he's on the road, but it's extremely non-sexy; Scott and Rob watch it with Lamar, who thinks it's a joke. Kourtney misses intimacy with Scott, but is afraid to have sex because she doesn't want to hurt the baby. She later takes a Sex During Pregnancy class with Scott, and begins to enjoy sex again.
