c'mon buddy, we should do something about it! to be honest, am in similar situtation and I always was.
one thing I am completly sure about - pornography is rubbish, but it's quite hard to get from it, especially if you have access to internet .)
You should definitely delete all the porn from your harddrive and ban the sites you were using to get it from. but the problem with this is that if you ban the websites yourself, you will know how to unban :/
I was never that kind of guy interested in porn, I just use it for masturbation. But have I won? No, definitely not, I wish I can return in time to the moment where my cousin firstly show me the porn and reject it.
I don't think that masturbation has to be bad thing, but in combination with porn it takes more than it gives. I always feel better (inside, around womens, clearer thinking...) when I have week or more off, but then I will do it once again :/
I am doing both gym training & running, but I still find middle-part of my body weak (weakest part of the body), causing some flatuance and digestion discomfort. And am pretty sure that it will get better when I will finally untie myself from doing this.
So what to do? Have done with porn, increase the amount of days without masturbation and find something what you should do instead of it (meditation, kegel exerciese, ???)
