When Jo Beth wasn't working or sleeping or aching, she found
time to hook up with a steady boyfriend who she had already
decided was to be her husband.  They weren't sharing an
apartment, but they had gotten to the point where they
sometimes shared a bed.

One day, just as she climaxed, Jo Beth got a horrid menstrual
cramp.   Then, it clamped down and got even worse.   It was so
bad that she couldn't stand.  Jo Beth slid off the bed onto the
floor, and, while her boyfriend asked "What's wrong?  What's
wrong?" she crawled around the corner into the bathroom and
vomited repeatedly from the pain.  When she stopped, she was
cold all over from her sweat.   The worst cramps imaginable.

And it wasn't even her time of month.

From then on, whenever Jo Beth came, so did the cramps.  She
could have sex, so long as she didn't enjoy it too much.
