There's no explicit mention of masturbation in the Bible, so Christians are divided on the issue. Some believe that it's intrinsically wrong, while others believe that it's only problematic if it becomes an addiction or if it prevents you from fleeing sexual sin. Personally, I don't believe that touching yourself is a sin. I think it's a perfectly natural way to explore your own body and sexuality. However, like anything else, there can be a downside to masturbation if it becomes compulsive or if it replaces healthy sexual intimacy with your spouse.
