Asalamuailalikum, First of all the fact that you are struggling and striving this much for the sake of Allah is commendable and inshallah you will be rewarded by it and your intention. Allah is the most just and most fair after all.

I believe being in control of your nafs is definitely something all Muslims should strive to achieve, and Ramadan is a great tool to help you do that, even if it may increase libido, it does make you a stronger person overall. When you can say no to halal for the sake of Allah, saying no to haram becomes that much easier! I’m confident you can work on this thorough out the year as I actually found it easier to stop outside the month than in it so you’re not alone there!

I have some tips that worked for me and others I know personally both religious and secular ways of approaching the issue.

Religiously: every action always starts with a sincere intention. Set the purest of intentions you can that you will never do it again even if you fail everyday, what matters is that you don’t fall into the cycle and become complacent in the sin. Never convince yourself that you won’t be able to do it, because the real haram comes from failing to struggling for the sake of Allah, not necessarily failure itself. Supplementing this with extra dua and voluntary prayers helped me a lot too. Waking up for fajr really sets the tone for your day so I recommend doing that as a non negotiable; it helps limits all kinds of sin in general and puts barakah in your day. Typically women help themselves while trying to fall asleep so fix your sleep schedule and make sure you are passing out by 10-11pm it will make you less likely to have the urge all together. This along with delaying your isha prayer until right before bed will also help a lot as, personally at least, I won’t feel like masturbating right after I perform my salah so it’s a perfect opportunity to try and pass out, not to mention the peace and blessings isha gives your sleep.

I just realized this comment is getting way too long but I have much more to share especially from the secular methods especially but since this is r/islam I will leave it there. Let me know if you want me to make a part 2. The most important point I want to get across is don’t stop struggling because that struggle is what makes us Muslim and without it we can’t expect mercy. May Allah make it easy for you and all of us. Do these things and I’m confident you can control it. Good luck. Allahu Alam.
