Masturbation within a marriage is a perfectly normal and healthy thing to do. Couples that masturbate either solo or as a couple generally tend to have healthy sex lives. Masturbation allows a person to get to know their own body and discover their likes and dislikes. This information can then be relayed to your partner so they also know how to please you. If you don’t know what you like sexually yourself how can you expect your partner to?
Becomingly familiar with your own body is an empowerment tool. There is no shame in masturbation, it’s a perfectly natural and healthy thing to do. Some people believe that if their partner is masturbating it means they are not sexually satisfying them. That simply isn’t true. The truth is that the more a person has sex or sexual activities the more they will masturbate. That means if your partner is masturbating it’s a good sign.
Having said that if the masturbation is having an impact on your coupled sex or sexual activities that can lead to problems. For example, if your partner doesn’t want to engage in sex with you but still wants to masturbate there is clearly a problem there. The best thing you can do in that situation is talk to your partner about it. It might be a hard conversation to have but it needs to be done. Try to remain calm and don’t get angry. Simply explain to your partner that you don’t understand why they still masturbate but don’t want to have sex with you. There will be a reason and it would be good for both of you to get to the bottom of it.
