All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
We would like to congratulate you on the blessing of repenting from responding to such evil homosexual inclinations, and we ask Allah, The Almighty, to increase you in guidance, piety, and righteousness.
As for looking at marriageable women in order to treat those homosexual inclinations, it is similar to curing a disease with its like. It may even worsen your situation and expose you to another form of Fitnah (temptation) from which you are safe now.
We advise you to turn to your Lord and ask Him for whatever you wish; He is Able to do all things, and all things are easy for Him. You should also recite Thikr (expressions of remembrance of Allah) and Quran frequently, keep the company of righteous people, and attend their gatherings. We hope that all this will help you achieve your goal. If you are not married, you should hasten to marriage as it helps you maintain your chastity. Through accustoming yourself to being affectionate and intimate with your wife (even as affectation) through foreplay, playfulness, and affectionate speech, it becomes a second nature to which you would adapt.
If you believe that you need to see a psychiatrist, then you should choose someone who is reliable, experienced, and specialized in treating your condition.
Allah knows best.
