questions about having HOCD,intrusive gay thoughts and delayed ejaculation

hi there guys! I'll get straight to the point! I have hocd,intrusive gay thoughts and somewhat of delayed ejaculation
I have a girlfriend,I'm able to have sex and reach climax(it takes a bit but not really too much) but since 5 years ago,I've started to switch with a kind of different porn material( hentai traps or futanari((girls with penises)) and since then,it looks like I'm attracted to that kind of stuff,I don't masturbate to it since really a lot,everytime I do It I experience uneasyness and feeling wrong in general,like it wasn't meant for me,it all happened because one day I've started having hocd and fear of being gay,I've started to test myself with gay porn and then after a while I had a positive reaction(also only to the penis,like I don't like man they disgust me,even porn with them,but if a girl has a penis it excites me,but also disgust me) I have several questions: If I continue to hold this problem and not fix it,Am I going to get mind illnesses? like serious stuff?(schizoprenia,PTSD) I always feel sad and on low energy,Also Why can I have normal sex?(I have a lot of libido,like really a lot,I think of sex too much) and feel strong acrtraction to females but not for males(only the penis and it must be on a female),what can I do to fix everything? thank you for your time

What do you do in life? What are your activities?

Keep getting your NoFap streak higher and higher and focus on you and your life, not on porn. The urges will weaken, the gay thoughts will disappear.
Get a decent sleep pattern and eat cleaner, it will help.

thank you dude for the reply! the thing that I'm most concerned is the possibilty of becoming ill of mind illnesses like I dunno..schizophrenia or other stuff,I know it may sound stupid but because of the fact that I'm Always stressed and anxious because of this problem,I would like to know if it's gonna become a real threat later if I don't fix the issue right away
Btw I don't do a lot things daily,I've got my high school diploma last year and right now I'm searching for something to do for the rest of my life,this year I took a break for a lot of time after ending school
Thank you a lot for the reply

I can't tell you exactly but it's sure that if you continue this awful habit you'll have mental problems yes. Stop porn and other bad habits and you'll feel much better.

Ok so you have a lot of free time. How will you use it? You don't know what you'll do next, what do you do to find it? Do you have a hard time filling your days? (I do, sometimes )

Thank you again for the reply, no I don't have problem
Filling my day, usually I play with videogame, go out with friends or girlfriend etc, Also..seriously? Mental problems like the one I mentioned?(schizophrenia etc?) or just depeer depression?

I don't man... I don't want to say something stupid.
PMO will make your life miserable, that's a good enough reason to quit I guess
