Any 60-70 yo guys here?

67 still fit and healthy, married to a 53 year old very sexy wife! She likes me to be smooth shaved, but sadly I now need viagra to get hard plus my penis is shrinking with age - was 6” plus, now struggling to reach 5”! I’ve been a compulsive masturbator since I was 13, and still enjoy a good wank over full blown sex.
