I've shared that I was around 10 when I was exploring our attic and found my dad's stash of nudist magazines. I immediately went into the bathroom and started checking them out. What to my amazement I got a boner!
Well... I soon learned to rub myself into a dry orgasm...
Soon I was looking for another way to stimulate myself and discovered our vacuum cleaner... I turned it on and discovered wonderful vibrations. Soon after this I was looking for anytime I was alone ay home...
As I developed my cock was ... er... maturing and was soon to wide to allow the air flow which provided the vibrations!
I then took the cardboard from a paper towel roll and it gave me the right stimulation!
Now.. at 70+ I have issues with getting an erection... SO... Besides experimenting with Estim... I use a Craftsman Shop vac with a sock lining the hose!
Guessing old habits die hard!
