Has anyone ever had a panic attack right after sex? From orgasiming and breathing too fast? Today my boyfriend and I had really great sex and right after I had an orgasm my heart started to beat really fast and my breathing was really fast and off from how I usually breath...i started freaking out and crying b/c that was so unusual. Thankfully my boyfriend calmed me down and was being so patient with how I was....I just want to know if this has happened to another woman, or if it's normal ?
