If you can imagine your healthy sexuality, you could record your own self-hypnosis session. If not, you can learn it.
By the way, what is your problem?
If it's just a fetish, learn to live with it. Enjoy it.
If you spend too much time watching porn, learn time management.
If you have premature ejaculation, buy medicine or use hypnosis to get over it.
If you are slightly depressed or addicted to something, if you perform digital self-harm, or if you are suicidal, learn cognitive behavioral therapy.
I had all these problems (2 years ago when I was 20 years old) blaming porn and my human experience. At that time, in complete solitude after a suicide attempt, I made the decision to live my life as well as possible, because it could potentially make a practical difference/ create value for someone and I did not care about my life anyway. From then on it went uphill.
My experience was that I could not trust my intuition and ideals, so my advice is that you should as much as possible linger on effective and professional behavior and techniques. I did it this way and I have a good normal life today. Having said that, it was a rather long process and therefore it is clear to me that this forum can not help you enough (even if you just cannot accept your fetish). You have to find your own way and build your self-esteem (aka self respect and self efficacy) or you go straight to a therapist which is probably the best. I can assure you that you will regret it if you solve all the problems on your own (as I did), it takes too long and is the hard way compared to get help from a competent empathetic therapist.
