WTF HAPPENED

Hey guys,

I was on my day 15 of no PMO and I was going to bed. Before, I felt completely fine, and in general my erections were strong but I wasn’t VERY horny as some other users have reported. I would like to add I was not a heavy porn user, and only watched vanilla porn about 3-4 times a week for about 2-3 years. Anyways, what shocked me was as I was going to bed, I felt a rush in my body. I felt very horny but I didn’t want to, it was like my brain was trying to do something but I didn’t want to do it. I wanted to keep my PMO streak up and abstain from anything and everything sexual. HOWEVER, suddenly, without any sexual thoughts and I didn’t even touch my penis, I orgasmed in my pants. I tried to stop the feeling for about 15 minutes but I couldn’t sleep. I even tried to do squats to make the feeling go away. Just as I was about to transition from my resting state to sleeping, it happened, and my load was larger than usual. I am concerned because I didn’t even M and didn’t use P and didn’t have any sexual thoughts. Kind of like a wet dream except I was awake and I didn’t have sexual thoughts. Can anybody plz tell me what this is and if it’s normal? Should I consider this as a relapse and reset my counter. I am having mild symptoms that come with a relapse such as depression and anxiety, but not as bad as I had them before. Any help would be great thanks.
