I used these balls for about a month to try and strengthen my kegals. Before I heard of these balls I had no idea what my kegals were and how they work. Apparently, they help with orgasms, so I was more than willing to try! The balls were easy to put in, and comfortable to wear. I wore them for a few hours a day, and sometimes I practiced squeezing the balls to see if I could feel them. The real test was rather or not they helped me orgasm better. Well, they definitely get an a+ for that! I plan on using these all the time!!
