Tingling after sex

I've noticed this recently during and after sex. At some point, usually the part of heavy breathing, I get extremely tingly all over my body. It doesn't hurt, but it a very oddd sensation. I'm used to have tingling thighs after, but this is strange. It lasts anywhere from 1-2 hours afterward. Any ideas? I am taking some anti-histamine and some other nutritional supplements, could any of those be causing this. The tingling is somewhat invigoratiing, but also draining and it feels like it makes me a bit weak for the most part, maybe just because the sensation, after the physical exertion of sex, is overwhelming my body. Help you if can.
