This is crucial. You see, aftershave on your face helps soothe skin and smells nice for a bit, but on your balls, it plays a much greater role in reducing the risk of irritation and possibly infection. As blood is thicker than water, pubes are thicker than the rest of your hair, and as such, are more likely to become ingrown. Find a good quality alcohol-based aftershave and apply it liberally – not just straight after the fact, but in the following days too.
