I typically use one of 3 methods when doing it by hand:

Thumb & 1-2 fingers just below the head, right on my frenulum, and stroke up & down.

Whole hand around the shaft, stroke up & down and roll my loose shaft-skin over the head on the up-stroke.

Rub my frenulum lightly in a circular motion with a forefinger. (That gives me the most intense & long-lasting orgasms!!)

I always used my foreskin whilst masturbating out of habit more than anything. Then one evening a few years back on my laptop webcam I was jerking with a circumcised guy from the USA. We compared techniques and he asked if I ever jerked my exposed glans. I pulled my foreskin back for him and started to stroke the ridge of my exposed head. To say it was a revelation is an understatement. Although being intact my head was quite sensitive I soon learnt to stroke it lightly building up momentum. Eventually my whole body was trembling and eventually I had the most intense orgasm through jacking off ever. Since then I’ve never used my foreskin when jerking off, it feels so much better exposed.

Put plenty of lube in the palm of your hand; grip your cock and put your fist firmly on a flat surface in front of you and then fuck your hand.

Get a silicone masturbation toy ("sleeve") and use plenty of lube when you JO with it. In addition to using it with your hand, you can wedge it under a chair cushion and fuck it.

Based on the numbers in your name, I'll guess you've already experienced the pleasures of jacking off after smoking. Weed and porn are the perfect accompaniment of an extended edging session.
