How should i masturbate

[tgon]

Hi, i'm 19 years and need help.
I'm virgin and i never masturbate. I only had pull the skin that is on my penis head to the back(in my direction). I pull it and i can see all the head, then the skin stays right behind the head and i start to pull more back but i don't know. To i masturbate it's already all done or do i need to pull more. Because if i pull i start to feel that it might be a lot and may bleed, and when i do this my penis doesn't get much bigger, starts to decrease a little and i don't have much space for that..

When i get erected the skin should go all behind the head? Because it wont go i have to push it a little but it's fine..
I can do this without an erection with no problem, with erection i have to put some spit..

Hope some reply's please.

When masturbating, always use some lubricant on your penis, whether it is spit, petroleum jelly, liquid soap, baby oil, and so on.
