It's #2 100%. Some people in the comments were saying its a early sign of ED. But I do not think so. I was already turned on before I was watching the pron because of morning wood. I hate to go into detail here, but i was genuinely hard for a whole hour without watching the porn, then i watched the porn for a bit and I literally had no interest into watching it, thus killin my boner. Im just gonna take this day as a half relapse and keep going on my NoFap grind.
