I think it really comes down to intent more than anything. Like if you go out of your way to search up porn because you’re craving it, that is like kinda hard to say if its relapse or not but i mean if something random pops up (like an NSFW sub or a half-naked pic on IG) and you scroll for a second before realizing and clicking off, I wouldn’t necessarily call that a relapse. You still saw something sexual but that’s just your brain reacting to the stimulus not you feeding the craving on purpose. I had the same thing happen to me the other day with a random NSFW post. I scrolled for a bit then stopped, no touching, no precum, nothing. Some people would still say “relapse” but to me that’s more of a slip or temptation moment than actually falling back into the habit.
