my beau is 68.. and since I've been seeing him on and off for almost 40 years I can safely say that while I don't see any "droopage" in his ball sack area.. i do see extra wrinkles...
Doing
kegels will help with sagging pussy lips and the falling bladder issue.. but time, for all of us, marches on.
On a good note.. I have found that getting older, the sex is better. not pro-creation sex.. just sex for the fun of it.
