So after my girlfriend started using ben wa balls she hasnt been able to orgasim from sex. She hasnt really had a problem with it before. She still cums from oral sex but other than that she says intercourse doesnt feel the same. Could it be that she over worked he kegal muscle from using the balls to much. SHe hasnt used them in a couple of days and is still having issues. Is the anything we could do or try to make it better?
