Well one thing you be sure to do is clean underneath the foreskin. My mom (I lived with both parents) was the one who taught me to bathe myself but she never taught me that part. I didn't start until around my teenage years and I do it every day.
Having some "you time" isn't bad at all. There are muscles around the male reproductive system. Like any other group of muscles, keeping them healthy through exercise (if that's how we'd like to put it) is a good thing. Too much? Is a bad thing. Also I like to take Saw Palmetto because it's good for prostate health.
