No, other than feeling frustrated and being a uncomfortable physically there is no effect on women.

WRONG! It is possible for a women to get a stomach ache from lack of orgasm.
Its not life threatening and I doubt it can harm you but it does ache just a tad bit.

I'm always open to learning something new, angel507ny. How does sexual tension or frustration cause a stomache ache?

well detergram Im not a doctor or anything and I never said frusteration caused a stomach ache but in my case I was trying to get some sexual intercourse and my partner ended up not being able to fulfill the deed and my stomach started to cramp up.
Google search female blue balls, you will be surprised!
Its not in all women, I just so happen to have experienced something like it.

Hey angel507ny
What your describing doesn't have a medical connection to unfulfilled arousal in women. However strong emotional reactions often have a profound impact on digestion, hence the direct connection between stress and ulcers.

ok never mind then. I know it happened to me maybe im the only person in the world to have a stomach ache. EXCUSE ME!

I know for a fact that at least two of us have had them. I also know that it's true that extreme anger, fear or frustration can turn an empty stomach into a painful knot, even cause some muscle cramping in the chest and pelvis. I'm certainly not saying that you didn't have a reaction to being left high-and-dry but I just haven't heard of any way the issue could work along the same mechanism that blue-balls does for men. If there is a connection I'd love to know about it.
