Need advice on my stretching technique

I am little confused as I noticed there are two different ways to stretch. Firstly I am uncut and when stretching with retracted foreskin, putting grip just behind the glans my external penis stretches long and thin but it puts out a lot of pressure on my glans so I can’t pull with lot of force. My glans gets little bit blue so I need to jelq few times before next stretch. Also with this technique I don’t stretch skin.

Stretching with foreskin covering my glans my external penis doesn’t stretch as good as in first technique but it seems it hits internal penis better, maybe because I can use greater stretch force, but I get unpleasant burning sensation probably because of skin stretching.

My question for stretching pros is: What is correct technique and if first one how to enhance grip, if second one what to do with skin stretching. Or should I maybe find solution somewhere in between this two.

Thank you a lot in advance, need as much opinions as I can get on this!

If you are uncut, you dont want more skin.

In my opinion you need to use the retracted foreskin technique, but slowly condition your glans to withstand the grip better.

Go bit by bit increasing the workload.
