I see many people here struggle with overcoming masturbation and pornography, I had that same problem and used to do it on a daily basis, but now it's already been over a month since I don't do any of this, and I feel I should spread the name Saint that helped me overcome this. He's Saint Expeditus, a military Saint from around the same period as St. George.
I just randomly upon his name while on the internet and got curious since I had never heard about him before. I got very inspired by his story and prayed for him to intercede for me. That turned out being very good, I deleted any porn from my computer, and differently from the other times in which I had done this, I didn't wanted to download them again. Sure sometimes I got tempted but never went for it again.
I'm much more disciplined now and decided I should spread his name, I'm not going to tell his history here since you can find it in much more details on the internet but I highly recommend any Christian to go look for it, even protestants who may not believe in his Sainthood but I still hope would be very inspired by his story.
I also encourage anyone to come here tell any story of overcoming vice through prayer or similar experiences involving you or someone you know.
