Yes it's probably fair to say that those without a partner probably masturbate more often than those who have one. But that doesn't mean people in loving, sex filled relationships don't masturbate. If you're one of the lucky ones, you probably enjoy masturbating together as part of your exciting sex life. In fact a recent study shows that 50% of respondents have used a toy at least once in their lifetime. 40% of women admitted using a sex toy with their partner during sex or foreplay.
