In humans it is believed that regular sexual activity ending in ejaculation promotes prostate health and the cleanliness of the penis and it's surrounding skin. Real sex is considered best but masturbation holds a close second. This makes me wonder if the same is true for intact male dogs. Are intact males that have sex often (either the real thing or a human simulating it with their hand) less likely to develop problems with their sex organs? I am wondering about this. Anybody know?
