I feel kinda stupid for even asking this.. but has anyone since they lost weight able to feel their tailbone?? Weirdest thing.. I can literally reach over and feel the tip ( alost like a round socket) of my tailbone sticking out when I bend over. I used to have a nice cushion on my *kitten* now all i feel is tailbone. Is this normal or damn maybe I'm growing a tail LMAO!!!! I'm also wondering if it's because I do Spin classes and am always landing on my butt.. Stupid question but I thought I'd ask. Im one of those people who worry about anything and everything.
