Rhapsody stole the words from me!

Tilted uterus is very common, particularly if it's tilted backward. Gyno's have told me that approximately 25% of women have tilted uterus.

Prolapsed bladder can cause a lot of pain as well, as it presses onto the uterine walls.

Another possibility is not enough lubrication. Lots of men want to make love before our bodies are ready and lubricated well. That causes a lot of scraping and bruising. So the pain will last a couple of days. KY Jelly works great by providing gentle lubrication (gentle= low chance of skin irritation)!

Changing positions can help greatly (with you on top, or side to side) as well. If pain is really intense, see a doctor. There may be something physical, or psychological, in the way of your enjoyment.
