Porn causing trouble

I am straight male fully straight attracted to females in real life but this porn causing me trouble, first when I was in my 11th or 12th, I started watching into transwoman porn. I started watching porn in my 7th class and from that first few years I saw immense porn in the straight category and then after 3-4 years I was bored of that and I slowly started moving into transwoman porn I know it was wrong also wrote a thread for that few years back but now I have started normalising it I open transwoman porn and masturbate to it in initial days there was some resistance to it that I thought it was morally wrong I am only seeing a converted guy but I watched it more and more and as I watched it more I slowly normalising it. and now I am in my 2nd year of college and after 3 years I first saw gay porn and in that moment I went to omegle to sew trans women and also asked some men to flash thier dick while seeing porn I don't know I loose control over my intelligence and started doing things which I never thought off. I am a straight male attracted to girls but this porn has changed my dopamine of my brain making me go towards the porn more extreme or more out of the way I have not seen. I am a sober guy pretty much sober also achieved many things but I am not able to get rid of this porn as of now. I want to get back to normal not masturbating towards transwoman or gay men. Anybody up for a help and can tell how I can normalise myself
