I tried to quite a couple years back (well not just tried, I did) I mean obviously I didn't quite for good as I am here, but, I did quite at the time with out it being a issue of having withdraws and such
gained it only last a about a couple of month tho ironically it was because about a month in I hooked up with this chick (after a very long dry spell, of not having sex) and found that having gone that long (in addition to not having had sex) but not even having jerk off, I found that it rather hurt my performance
but still even after that I still didn't start up again for another month or so late, as once again i found my self with a girl, an again had and rather quick performance, after that I started flapping regular again, (not even to porn at first, just flapping it before bed a few time a week) just to you know release a little tension
an the next time I found myself with a girl, it paid off as I lasted much longer and even preformed multiple times, without problem
so I leaned that a little masturbation here and there is healthy and normal, even if your using porn to help you get there ;) lol
as long as you don't let it take over your live
