Penile clamps. They may sound unpleasant, but for certain men, penile clamps -- also called "external compression devices" -- can make a big difference. A small amount of pressure exerted on the penis can temporarily close off the urethra, stopping any potential leakage. The part that fits around the penis is soft foam and shouldn't be uncomfortable. These devices aren't right for everyone, so talk to your doctor. Using them too often could cause circulation problems, skin irritation, and strictures. Generally, they're only meant to be used for a couple of hours at a time.
