This may be a little TMI, but sometimes during sex the angle that we are in will become painful, and even if I adjust, sometimes the discomfort continues.  My husband and I were intimate yesterday and at the very end, I was experiencing some pain, and even today I feel sore- I'm not doubling over in pain or anything, but usually it doesn't last long, so I was surprised I was still feeling sore.  I ovulated last weekend, so I'm not sure if it's related to that, or if we just hit a bad angle.  Anyone else ever have that happen?
