I am a 38 year old female. I've had this problem for some years now and it usually happens a couple days before my period starts. In the process of having great sex or after orgasm my stomach starts to hurt. The pain gets worse and worse and is followed by nausea. Sometimes I vomit and the pain gradually comes to a stop. All this will last for about 5 to 10 minutes. When it's all over it's like nothing happened. I am in really in need of some reasons and solutions as to why I have extreme stomach pain during sexual excitement. Please help! Oh I am also a diabetic.
