I had that same pain for maybe two months or so after surgery. Probably three months when I had gas or needed a bowel movement. But it is long gone now.
Pillows or folded blankets worked well for me. I made one out of a piece of foam that came in a box as packing. Worked well.
People are all different. I would rate my orgasms better than before. Give things time. Hurring and worrying do not help!
Keep on Keeping On!!!
