Is it normal i mastubate when i'm upset or depressed?

This is actually the best comment here, no idea why it has negative points. It is true that masturbation/sex biologically makes you feel good/happy, at least for a moment. So it is perfectly normal to feel desire for it and do it when you're sad. It's natural. It is also true that it won't help in the long run and if you're feeling down so much, it's probably time when someone help you, motivate you and when you start doing something about it instead of just covering it up. In this case it;s very much like an alcohol or drug addiction, you gotta be careful and keep a balance in doing various things.
