Cock Ring Or Silisleeve After Pumping

Hello all,

I think I am starting to break my plateau with the new equipment I got.

I did jelqs starting out and gained a little over half an inch -then nothing.

I got the Penimaster Pro along with the MityVac.

I jelq 250 times 3-4 sec each rep and then I pump for 15 to 20 mins.

Is it better to use a cock ring or silisleeve after that session? Can I use both? How long should I wear it for? I think I read 4 to 8 hours but not entirely sure.

I also use the Penimaster Pro Extender about 4 hours after for 3 to 4 hours taking 10 min breaks as needed.

Let me know if this regiment is ok or if I am overdoing it. Thanks!
