Abstinence from Masturbation?

So I've decided to abstain from masturbation. It's been 10 days and the urge to do it is killing me. I'm wondering if it's worth it: what are the real pros and cons to masturbation? I know the obvious pros (it feels good, can relieve tension, can help reduce risk of prostate cancer) and cons (distracting, addictive, can lead to porn and worse things), but I'm looking for the kind of answers that are genuinely thought-out and involve personal experience and/or scientific backing. How has it affected you emotionally? Physically? Socially? Does it impact your life at all? I've had many experiences, but I'm looking for outside opinion and thought. If you're just going to say "it feels good" or "why wouldn't you"–don't answer, please.
