Holding shaft while stretching

It is much easier to do simple manual stretches (down, left, right) when you hold the base of the penis with left hand OK grip.
In this way it’s also easier to hold right hand grip under the glans and push out.
Also I feel stretch to be more effective when I hold the shaft with one hand.

In simple manual stretches video I can see that that guy is using just one hand and he use another one just to intense the pulling.

Should I stretch strictly as explained in the video?

I’m stretching as shown in the video, using an overhand OK grip and pulling down, left and right. During a stretch, I apply more pressure towards the end. Before I used the video’s method of stretching, I stretched kind of like you do now. But I feel a huge difference (in positive way!) now that I stretch as told in the video. You should see what suits you best, I guess.
