Anal muscle relaxer

Ok ladies!!! A while back someone mentioned a product that helps relax the muscles to enjoy anal more. She said it was great & she's enjoyed it since using whatever it is. I want to buy one but I want to hear personal experiences with the products because once I bought this cream that's supposed to make your vag tighter & make sex feel like your first time but it didn't work for me AT ALL!!!! My partner at the time didn't feel a difference either. Let me know...
