Masturbation is a perfectly normal thing to do. It can be a great way to know your own body and your own sexual response (e.g. what it's like to have an orgasm). You can discover what kind of touch feels good (you can share this information with a partner if you have one). Masturbation is something you can do whether or not you have a partner. It involves no risk of sexually transmitted infections (STIs) or pregnancy AND it can feel good.
