Masturbation is very common and a normal part of growing up. Most people realize that masturbation is a natural way of exploring your body and should not be thought of as shameful. However, if you have grown up in a culture and/or religious community where masturbation is considered wrong or immoral, you may feel ashamed for feeling sexual pleasure. Masturbation will not have any negative effects on your body or interfere with the medicine you have been prescribed to induce your period.
