Ever since you made this thread, it has been on my mind on and off, and what turning to a fantasy reality can actually do to your life.
I wouldn't really consider myself an addict, but what I noticed was that I would turn to it a lot of the time when I felt frustrated or angry, or something I wasn't happy with. My marriage has been on the rocks for around 3 years and we hardly had sex and I reverted a lot to all my hobbies and things like that to isolate myself from all the ******** we were going through.
After a period of separation we are now back together sexually, and I am having trouble keeping an erection. Online, no issue... for a few minutes obviously. I now strongly believe that my actions of turning to this has caused this, and I was escaping my issues rather than dealing with them. I also noticed myself getting moody, which is kinda weird.. but it happens.
My wife is extremely supportive, and I will be stopping looking at it, and getting help. I am positive that in time I will be fine again. I strongly believe that it damages your mental state of mind, and your sex drive. I would assume that most guys these days look at it, and I still find it incredibly brave of the OP.
I have had a lot of hard lessons lately, mostly involving me admitting the person that I am. This is just one of them.
