I usually stay up late. In this case, I was up until 3 am in the morning. I had masturbated two hours earlier, but I decided to do it again. Afterwards, whilst it was past 3 am, I started feeling my heart beat against my chest. Even now, I still feel it. It's incredibly annoying and I don't know what to do. Is is the masturbation? Staying up too late?
Is there anyway to fix it? Does it go away with time? This constant pounding from my chest is so annoying.
