Hi, Masturbation is an every man's habit. Its a safe outlet for sexual urges of unmarried men and men without a sexual partner. It does notcause erectile dysfuction. It satisfies your sexual desire, so you may not feel that much urge when you masturbate regularly. It is not a problem. It is like 'not feeling hungry' when you eat regularly.
Next Steps
Anyway you have reduced masturbation. That's enough. Things will come to normalcy soon. If you still feel uncertain or worried, please consult privately.
