Age 70 here. Have not yet experienced the saggy balls bit, but I have noticed a decrease in how hard I get.
As far as size, it doesn’t really change but, we do gain weight as we age, and the fat at the base creeps outward shortening how far the penis comes out.
I had gained almost 60 pounds and lost two inches.
I then lost it all and gained my full length back.
I have since regained 30 pounds and lost one inch of penis.
It is enough that it bothers me, even though I started with 7 inches, I still prefer my full length and will lose this 30 pounds to regain that inch.
My husband actually liked it when I was heavy.
Normally, my dick was at least an inch longer than his, but when I gained the weight, his was longer.
