I thought I made a mistake purchasing this after using it the first time. There’s definitely a learning curve and patience is required. Once you figure out how to tighten your muscles and keep yourself on the edge several times before allowing an Orgasm it’s very explosive and pleasurable. I usually keep it in for about an hour while teasing myself until I can’t wait any longer. You do need to purchase batteries from 3XToys and fortunately I did because I couldn’t find N size batteries anywhere locally.
