Kinematics of coitus in five pre-selected positions
Natalie Sidorkewicz carefully analyzed spine and hip motions of ten couples each having sex in five positions. Sidorkewicz wrote it up, as her master’s thesis : “Lumbar Spine and Hip Kinematics and Muscle Activation Patterns during Coitus: A comparison of common coital positions,” Natalie Sidorkewicz, Master of Science thesis in Kinesiology, University of Waterloo, 2013. The main objective […]
