Reverse jelq?

Hey what do guys think about doing reverse jelqs for base girth? Just a jelqing motion but towards the base. I have experimented lightly and they feel kinda good. Not sure if it damages the valves though.

Any ideas if this is safe or not? I am worried it might damage the non return valve, but I’ve been doing it the past week without any ill effects.

I do this sometimes. I will also sometimes grab near the head and try to push it back towards my body. Feels like it strengthens the base although you should be careful to not be reckless.

Also, reverse jelqing can cause blood to pool in your undercarriage so if you don’t get the blood circulating afterwards you might get aches in the prostate region hours later.
