Hi! This is very private, but early today during masterbation, my heart rate went up ALOT, so I stopped to take a deep breath, and when I did, my whole body, starting within my chest, and down to my abdomen, started burning unbearably. I was in so much pain I couldn t move. I then got up and moved around and it went away. But I d like to know if I run any risk if I continue to masterbate. It s never happened before, but I certainly never want it to happen again.
