Should I use a clamp

I’m thinking about using a clamp to keep myself engorged after a workout to prevent any turtling. It wont be tightened properly just enough to stop it from shrinking.

I’m a newbie but feel like i have a lot of knowledge as Ive read up lots, so i would never consider a clamping routine at this point but was wondering what you guys thought about using this technique after a workout?
would it help?
and if so what sort of time should i keep it on after a workout?
