PMO has definitely made me bisexual, I was straight before doing PMO, can NoFap reverse it?

Damn man, I had the exact same thing. Unfortunately, I still haven't fully overcome it but that's probably because I've kept relapsing the past year or two and going back into old habits. However, when on my longest streak of 40 days, I don't think I thought about guys once. I was interested in a girl from school and was messaging her. I think I was honestly just in shock that she was replying to me (she's very popular and hot) that I didn't think about guys the whole time. It's a common symptom of porn addiction to "want more" whether that be: BDSM, bestiality, gay porn, or some other fetishes.

I think you should try Nofap for 90 days and in that time, try talking to a new girl even if it's just online (if you have a crush, talk to her). I think after so long without the porn you'll be so engrossed in this girl that you won't really think about guys. If you still think your bi after a porn detox and a relationship with a girl, then maybe that's just who you are. I'm still struggling to understand myself to be honest, but hopefully, I can do the same as you and figure it out.

There's only one way to find out, and that's to do the 90-100 day streak and see what happens. No one on here can really tell you as everyone is different. Besides, there's no harm in doing the streak anyway, only good things will come out of it so do it anyway! Hope this helped and best of luck to you.

 

I had the same issue, failed noPMO for many years, decided to do noP and that worked for me. It's not your sexuality it's just P addiction and you can recover from it.
