I think you've got it!

i love the feeling at the start, where you see some hot babe in a vid or remember something - a beautiful woman, something sexy - and I start to get hard and know i'm gonna feel so good stroking and shooting my load

Just writing this was tough because as I scrolled through the thread I began to really work my cock and didn't want to to stop and type. So two things, I really love the feeling of my well lubed hard muscle gliding through my fist. Feeling the muscle bulge and throb feeling the veins, mmm, all while enjoying how fucking good my hard cut cock looks, especially while it is being stroked. Last obviously working it until that magic moment when you just fall back and release your essence. Here I always pump through the cum, that is I don't stop jacking it hard as I cum so my jack stroke actually pumps my hot cum out while I can feel my cock at its hardest and most sensitive...Enjoy.

that first instant that i actually touch my dick, not just rub over my pants or underwear. that first bare touch is awesome.

For me, a big part of it can just be the anticipation and then the feeling of my cock growing harder and harder...usually I start to press on my cock through my pants (like I am now!) and do some rubbing. Eventually of course I let me erect penis out and just start enjoying it!

I enjoy knowing that I have the time to do it. The realization that it is going to happen in the first place is a big turn-on.

I enjoy both ends on the process. From pulling back my foreskin for the first time and then obviously seeing the final act of shooting a load across the room

That deep feeling when you're really getting into a stroke, you've got exactly what you need (porn, a particular fantasy, a good partner, or whatever it is) to get you truly aroused, you're relaxed into it with the time to properly do it, and you feel every stroke through your whole body, the tip of the cock slowly glazing over with precum, moaning and breathing deeply, slightly losing control and self consciousness but not so much that you can't control it and keep the feeling going.... Oh yes!

I love eating my precum and rubbing it around the head of my cock. Tastes and feels good.

The best part is all of it.
From the moment of excitement as I watch my wife pull out of the driveway to the aftermath when I lovingly wipe up the warm, creamy semen off my abdomen. Masturbation - the best part of living!

I agree with all of this, you've put it well, true masturbators get it!

The favourite part of masturbating for me is the very first moment that the precum starts to flow and I get to smear it around my cock head before tasting it.

All of it for me never ever got bored with masturbation

Hell yes buddy ... I live for that!

for me, it's finding the right video to finish to. Watching a lot of different types has given me ideas to use in my own sex life, and it's fun finding the "right" one
