Whenever I masturbate (does not seem to apply with sex) and I climax, my whole body seems to get a tingling all over, and my heart rate seems to drop significantly more then normal. Not a good tingling either, it feels very weird and I dislike it very much. It kind of freaks me out to and has only started occurring recently. The only thing that it seems like could possibly be causing it is the anti-anxiety medicine i'm on which is 20mg of Celexa. I am not sure though and was wondering if anyone has heard of this? I have not been able to find anything online about this.
