Have you ever turned him/her on by Stretching?

Okay, so I'm one of those people that has to stretch everyday or my muscles get cramped badly. A few weeks ago, I was stretching in front of my BF because I started to cramp up and he kept whistling at me every time I switched legs from left to right. Chinese torture is the one that he actually picked me up and tried stripping me. We didn't have sex because I told him to put me down. Is this sometimes usual for some people? Do you stretch in front of him/her?
