how to give a hand job?

i’m 17 and have never given a hand job before. i’ve tried watching porn but it all looks the same to me and seems repetitive, but maybe that’s the point.

does anyone have any tips or techniques that i could use? or is it all relatively that simple with the up, down, and twisting motions.

do i need to spit on it beforehand?

and how do i go about it in a romantic sense? i don’t want to just start getting him off because i feel like it would be a little awkward. do i just start rubbing him while we’re making out? how do i ease into it? these are the kinds of things that is not being shown in porn.

better question- what is the best way to go about this in a car? just so i can visualize it

(it’s a pretty roomy car)

SIDE NOTE: the guy that i plan on doing this with only has one nut LMAO. i don’t know if that changes things, or how i would play with that part of him.

ALL HELP IS APPRECIATED!!!!
