I'm 23 and have possibly been addicted to porn and masturbation since I was 14. I've quit for months at a time before, but it hasn't stuck. I've been married for nearly a year, and I've kept my addiction from my wife. It's starting to affect our sexual relationship. I'm not sure if I really am addicted or not, but since I can't always stop myself I assume that is what is going on.
I definitely advise telling your wife! It's a good test of character too.. How she reacts to it. Most women like when you open up to them and tell them things most men would never share with them.
I've been thinking about it, and I keep chickening out and justifying myself by saying it wasn't a good time. I'll let you guys know how it goes when I have the balls.
