Why would you want to risk it? The problem with porn addiction is that you've already created the 'porn' connections in your brain. Those connections might become weaker over time, but they'll never go away. It like if you learnt to ride a bike when you were 5 years old and then don't cycle again until you're 50, you might be a bit wobbly at first but your brain will still remember how to ride a bike.
I think it was after my third relapse that I thought I would recover more quickly because I had abstained for a long time. In fact I remember I was in a 'flatline' for over 100 days and it was about 200 days before I could have sex. The first time I rebooted I recovered in 38 days. Why did my fourth reboot take so long?
I'll tell you now, I'm a porn addict (I suppose you are too). There are no safe levels of porn consumption for an addict. You're always going to be an addict, unfortunately. It depends whether you are an addict who can fight the urge to watch porn or an addict who can't. Don't risk it.
