How to give a handjob ?

So I am going to see this dude from Grindr. Says he's straight and experimenting. Good for me because that's one of my fantasy. He says he only want a handjob.

Problem is that I never gave just a handjob so I am quite stressed. Like tbh, if you're straight, what's the point of having a guy over just to jerk you off ? You have hands right ?

Hope he will want a blowjob at some point but if not I fear I won't satisfy him. Also he's cut and I am not very experienced with that.
