If you like to switch positions this may ruin your mood but it definitely intensified our experience since my legs didn't get tired and were not annoying to use. It spread my thighs much wider than usual and kept them close to my chest without getting tired. The material is wonderful and very sturdy. It is not used for non-consensual sex as it's easy to take off with my hands without any other restraints like cuffs or rope. You can adjust it with having your hands restrained but I personally don't like using restraints unless I'm laying on my back and still comfortable.
