This is a two time occurence for me. First time was last November and second time was last night. In the middle of having sex I started to cramp up. After trying to avoid it, it just got worse. Next thing I know I'm bent over the toillet ready to vomit and sweating furiously. Neither time did I actually puke but did end up with a little bit of diarriha. Not fun. Then jumped in the tube to cool my body down and calm my cramps. This is really weird and I don't know what (during sex) triggered my temperary sickness. If anyone could help me out that would be great. I would really like to avoid this happening again.
