friend - I was just re-reading your OP and I think I kinda missed the boat on this one. I went off on a tangent, but I hope you have gleaned something from what I have said. But I will make a turn and specifically address a couple of issues, which seem to be at the heart of your inquiry: (intentionally taken out of order)
but my problem is, I still really struggle with my sexual desires. I have started masturbating pretty frequently (2-3 times a week)
You did not say WHEN you started this; but if you are normal, it would have been around 12 or 13, which would mean you have been doing it for about 10 years.
It's like, all my reason goes out the window when I start feeling lustful.
IMO that is by design. God designed the sex drive and works it hormonally. Hormones can have a huge affect on our mentality. Up the testosterone by itself and a person gets more aggressive. Up the dopamine and a person gets happy. Up the melatonin and a person gets sleepy. Lower the serotonin and the person gets moody or depressed. Up the ghrelin and a person gets hungry. And the balance of testosterone, estrogen and progestin affect sexual desire. All of these hormones have both physical and mental effects. They can distort your view of reality. And the desires and moods they create push the mind to work toward satisfying them. When you are very hungry or thirsty every thought is influenced by how to get a drink or something to eat.
These are all working the way God designed them to work. That includes your sex drive. It is part of God's design. IMO that is the reason He never (or almost never) answers the prayer to remove or diminish it.
Isaiah 45:9 NASB95
“Woe to the one who quarrels with his Maker— An earthenware vessel among the vessels of earth! Will the clay say to the potter, ‘What are you doing?’ Or the thing you are making say, ‘He has no hands’?
When you bemoan your drive, in essence you are saying to God that He should have made you differently. Trust Him that He knows best and has YOUR BEST INTEREST in mind.
Genesis 1:26 NASB 95
Then God said, “Let Us make man in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth.” 27 God created man in His own image, in the image of God He created him;
male and female He created them.
Right there it says God created your sexuality. And in verse 31 He said it was "VERY good." Again, that
includes your urges.
and after every time, I feel so gross and disgusted with myself but I continue to do it on a frequent basis. I don't know what to do and I feel so guilty and dirty and that God is disappointed in me but I can never seem to curb the urges.
From what I have seen, this is a rather common reaction to doing the "deed."
I would submit that your belief that "God is disappointed in me" is not accurate. Since the urges are part of HIS creation, trying to curb them becomes a work of the flesh which is bound to fail.
As to the feeling "gross and disgusted, guilty and dirty," you should ask yourself: Where is that coming from? It certainly does not sound like the conviction of the Holy Spirit.
There is a huge difference between the condemnation of the devil and the conviction of the Holy Spirit. The Holy Spirit
never leaves you feeling like God hates you. Rather, He is clean and encouraging:
"Yes you messed up and sinned, but repent and I will help you to do better. And all your sins are washed away in My blood."
That is what conviction looks like.
OTOH, if it is something like "You dirty rotten sinner, God hates you because you always mess up. You are not even worth the air you breathe." That is condemnation from the devil. And it is a LIE.
Reject it immediately.
I have already introduced you to Song of Solomon 5:2-5 where I submit Shulamite did the deed. Now lets look a little farther in that chapter:
Song of Solomon 5:6 NASB 95
“I opened to my beloved, But my beloved had turned away and had gone!
My heart went out to him as he spoke. I searched for him but I did not find him; I called him but he did not answer me.
7 “The watchmen who make the rounds in the city found me, They struck me and wounded me; The guardsmen of the walls took away my shawl from me.
8 “I adjure you, O daughters of Jerusalem, If you find my beloved, As to what you will tell him: For I am lovesick.”
Have you felt beat up after the deed? Struck and wounded? Like something was taken from you? I think yes is the answer. So did Shulamite. But WHY did she feel that way? Was this still part of her dream/fantasy? Or was it a poetic description of how she felt? Either way, it is best described as loneliness. Not guilt. Not condemnation.
Loneliness. That inner ache to be sharing that intimate moment with your spouse.
God designed sexuality to bring and bind 2 people together on all levels; physical, emotional, spiritual. Without that other person to share it with, there is an emptiness in the pit of the gut that can feel like guilt. I am sure the devil loves to work overtime on convincing people that is what it is; but remember the bible calls him a "liar and the father of lies." (John 8:44)
I would hope this will bring on other questions. Please ask and I will try to answer the best I can.
