Doing this for the first time and in the middle of a flatline, absolutely miserable

Hey guys, first time doing no PMO here. 35yo, been watching porn since I was about 12 or so. I read "Your Brain on Porn" and decided it was now or never. My porn habits have never really been consistent. There were times I was watching it multiple times a day, then times I wouldn't watch it for a week. But it's always been an easy "go to" for me when I needed a quick dopamine rush. The last few years my appetite started changing to needing more extreme types of porn. Stuff I never would've imagined watching and it made me hate and judge myself. On top of that I've had issues with getting/staying hard during real sex. So I finally stopped.

Currently on Day 12 and this flatline is just awful. I've been getting decent morning wood, but during the day my member is shriveled up and may as well not even be there. I've noticed that I don't look at guys with that same hunger anymore. I can tell a guy is attractive but that's about it. A few days ago I tried to have sex with a guy I went out with and it wasn't very successful. Try as I might I just couldn't get into it.

I know there are a ton of posts about this on here, but I guess I'm seeking some reassurance? Specifically for those of you who developed some weird tastes over the years. As I sit here writing this I can't believe what I lowered myself to getting off on. I'm super determined to see this through to the end, but starting to feel like I'll never be turned on by "normal sex" ever again.
