RTR,
Uncle Dan has remembered something very important, the donut pillow helps.
If you get an inflatable one, don't inflate it all the way.
The crotch area will be sensitive for a few weeks most likely.
The pillow helps for sitting and reclining.
Many here did expereince swelling in the scrotum.
Some just a little. Some quite a bit. It is normal.
If you experience it, it will go away in a few weeks.
You will feel better soon!
Your Friend,
