Hi,
i thought it was only me, but I too get a pain in my lower stomach, a dull pain.
I don't know what it means but I know that when the penetration is deeper thats when I get the pain, so we have been trying to try different positions to stop this happening. I think maybe though, I should see a doctor as I don't believe this is normal, sex should not be painful and if it is maybe our bodies are telling us that something is wrong.
