I wore compression underwear:

After day 10, I was comfortable with walking around. Resumed light sexual activity.
After day 14, I was comfortable with groceries.
After day 21, all aching symptoms were gone. Resumed regular sexual activity.
Buy a pack of compression underwear. Wear it for as long as you need to minimize movement of your scrotum.

I use compression shorts. These are fairly cheap for a 3 pack and do a good enough job. Have had them for a year and about 100 classes and have held up.
