advice on sex with a virgin?

so i have been talking to this guy for a while and he is a virgin and he's almost 18. in 17 and i lost my virginity at 14 and i have significantly more experience than he does.

things have gotten heated between us a couple times. i gave him head and he has a really low stamina which i can understand i guess. but he tends to get so nervous around me and he says and acts like he is ready but i really dont think he is.

i really want to because im needy lol and he says he does too but idk. any advice???
