I'm with GoodWood.... it's necessary to "keep the juices flowing", if you know what I mean. My doctor asked me if I was sexually active, and I told him yes, and that even when I'm with someone, I masturbate daily. He told me he was going to recommend that I masturbate, if I didn't at least twice a week. I said "Twice a week ?! I can do that easily in a DAY ! " He chuckled and said " you have a prostate like a 15 y/o, now I know why...." Its important to your health to stroke 'em , guys !
