Hi Deb,
you may also have something like endometriosus,I had it a few years back & had pain straight after sex, unbearable pain like a knife was being jammed up my butt! so the doctor lasered it all & have no problems now.I am 49 & guess at the time I would have been about 38. Go to the doc' asap & let them figure it out for you.
Have you had menopause yet?
