Basically he wanks like usual, but he stops just as he feels like he's gonna cum.
If he keeps doing that he should learn, & it'll come in handy for you. haha
basically when he feels he's about to cum he takes it out and either of u presses firmly under the head of his penis, this lowers his erection which means u can then start again
Not much you can do about it, except if you're doing handjobs or blowjobs or whatever sexual thing it is you do, then try going a little slower. Sometimes if you go too fast it can make him cum faster, and get him off sooner. Try it slower. It might work.

if he doesnt have a lot of experience... ill jus say it basically he should jus masturbate abput 30 mins b4, also what might help is if he doesnt "fuck" really fast early on, explore and have fun, messe around i guess..
