Belated birthday wish to you Tazz! Glad you made it past boot camp! Now that you're "seasoned," it's time to really get down to work!
Just turned 60 myself, back in December, and haven't slowed down a bit; in fact, I probably masturbate more now than I did as a teenager which was pretty much all the time! Let me assure you, as long as you use it, you won't lose it! I get just as hard, just as often, as I ever did. Of course, having a wife 20 years my junior and a budding step-daughter in the house probably contributes a lot to that.
Many, many more "blissful" years to ya' sir!
