Will the fantasies remain ?

IMHO, if your plan is defined as "sometimes stopping PMO" then there is very little chance that doing that will stop your fantasies.

Instead, if you're really serious about stopping, then I'd suggest that you reverse the planned cause-and-effect.

Since you have the power to decide where to allow your thoughts to linger and where not: make a binding decision to not indulge your thoughts in these fantasies, and this should go a long way towards helping you (not just "sometimes") stop PMO -- especially if this is combined with other tactics, like avoiding "triggers" ... etc.

 

Ah, could be that I misunderstood. @valky ?

In any case, I stand by my answer. The act itself of stopping PMO will NOT stop these fantasies, IMHO. On the contrary, the longer one becomes PMO-starved, the stronger the urges might become, and the stronger the lust to at least indulge the mind in fantasies!

And so, I repeat: everyone is potentially capable of deciding what thoughts to dwell upon, and what thoughts to "throw out" at any given moment. IMHO, this is not even that difficult. And although it is true that this same thought might come come back and try to revisit us (even countless times) like a pesty fly or mosquito, we have no choice but to chase the bugger away, each and every time! And if we're smart and know how to occupy ourselves with something else, then very likely we can succeed in achieving relatively long periods of quiet.

The point is that: It's up to us to activately assert our free choice for this to happen. It will not passively occur without our effort!

 

@valky - yesodi is correct in that we need to control our thoughts and urges.
Many of the over 40 group however report that quitting "P" can stop some of the fetishes that we have.
The longer we use porn the more "intense" or "stimulating" porn we eventually need to keep the dopamine receptors awash; to get our fix. It is this need for more "stimulation" that drives many people to stronger porn that involves the fetishes, or in some cases even same sex porn, even though the person is hetero. People report here that after abstaining from the P, the fetishes disappear. So it probably depends alot on how your fetish developed. Hope this helps you a little.

 

I found that obsessions regarding specific porn based fetishes quickly dissipated and even disappeared after stopping PMO. However, more primal fantasies of being with a woman/ having sex have remained. It is up to you how much you want to engage in such thoughts.

 

For me the thoughts about my fantasies/fetish left almost entirely after a few months of abstaining(maybe 2-ish months give or take a few weeks). I had, over 4 years of porn use, resorted to slightly more extreme porn, thankfully I didn't get anywhere near what some people on this forum have experienced, but after abstaining I basically no longer had the fetish and I thought of it as very bad because it wasn't something I would want to do in real life and it was important for me to bridge the gap between 'real life' me and the me that watched porn.
My thoughts also changed from having sex/penetration and orgasm with some woman to thinking about our relationship and love and stuff while having sex, it was a lot more romantic and what I actually wanted rather then the thoughts I had before that which were almost purely about just having an orgasm and not really caring about the other person or who they were.
When I fell back into the habit of PMO for 4-5 weeks the fetish which I had had came back, a lot calmer this time and it wasn't extreme anymore(I don't think I could ever go back to what I had once watched) but non the less it came back .
The thoughts about your fantasy/fetish definitely go away and they can stay away as long as you don't indulge them, however thoughts about sex won't ever go away, they aren't meant too, but your thoughts will change in terms of what happens in them if that makes sense.

 

If your porn and masturbation use was compulsive (I disagree with the addiction theory) then the fantasies will still remain. As time goes on, it will be easier to ignore them. An ex smoker or drinker will still think about their old vice occasionally. I know that from experience. Find out why you turned to PMO in the first place and work from there.

 

Yeah, I know what you mean. I agree.
