Hey,
I'm 22 and single as well and have been able to break free to some extent. It may seem to you that your fantasies get more out if c
ontrol when not "c
ontained" but it's actually the complete opposite. When you feed your fantasies in that "c
ontained" time your actually taking away c
ontrol from yourself. This is psychological warfare.
When you get a fantasy try not to focus
on it and force it out, just acknowledge and dismiss it without actually focusing
on it. After a little while you'll realize that these fantasies will come less frequent and less potent.
Try not to think of the struggle as such a m
onstrous task, try to
keep it to each day. If you get an urge or want to buy another ph
one then try to tell yourself that your not going to do it today. Each day is it's own challenge. The past happened and the future hasn't, you can't change what happens except for in the moment, so in the moment of the struggle tell yourself not now, now in this moment I am going to beat this nisoy
on. This is the c
oncept of ODAAT-
One Day At A Time. A lot easier said than d
one of course but with the right mindset it gets easier each day. Not easy but easier.
Also what's your motivati
on to get clean? Sometimes that helps to remind yourself why the effort is so worth it. My pers
onal reas
ons to get/stay clean is so that I can be free and be able to be an amazing husband and father devoted to his wife and children.
At a certain point of progress you will realize how amazing it is to be free with your thoughts in check and you not objectifying women. If what you meant when you said as a "single guy" that married men have it easier bc they have the ability to have a kosher outlet then your partly wr
ong
on that part. Ill explain just in case thats what you were implying.
When you use the sexual relati
onship with your wife as a way to release your taavos then its just a thing of lust and taking, when married there is a sharing of intimacy (intimacy ≠ sex) which is what builds the love in the relati
onship, if you use the sexual part of the relati
onship as something to feed your Lust then it will take away from the intimacy of your relati
onship with your wife which can/will lead to taking away from the love. If the sexual relati
onship is something at the peak of intimacy then it can help a pers
on with his taavos because he covets the c
onnecti
on/intimacy/Love with his wife more than anything Lust can provide. (Remember I am single so if I am wr
ong please edit/remove/resp
ond to this part of the post) Remember, Lust kills Love- Dov
Sorry for the tangent

I would suggest talking to HHM for a better understanding.
Life is so much better when not being c
ontrolled by Lust. Whenever we give in to Lust even when we think that we are "c
ontaining" it, we are just giving it more c
ontrol over us.

on't forget to ask Hashem for help in the moment!!!
Keep on Trucking,
One Day At A Time!!
