It helps if you get them to drop first. Rub your hand along the inside of his leg until he relaxes. I usually soak soft cloth pieces in slightly soapy water and wipe out the inside of the sheath that way when he refuses to drop it. You have to go into the tip of the penis and remove the bean.

If you're not comfortable doing it, ask someone experienced to do it the first time while you observe. Or have the vet do it and observe. The only real danger I've come across is the possibility of getting kicked.
