Close Call - Was this a relapse?

I'm two weeks in, and was flipping through some old sexts today, sort of messing around down there to see if I could get hard or if I was still flatlining. Then somehow found myself on an online dating site checking out hotties. The minute I realized what I was doing (replacing pixels for people), I put a kibosh on it. Maybe 2 or 3 minutes. Interestingly, by then I was hard. Have been flatlining for a while, but the pixels got me up and running. Pretty clear proof of addiction IMHO.

Anyway, have I set myself back to square one? Especially in terms of this flatline? Any tips to prevent this sort of stuff in the future? Thanks Fapstronauts!
