big🍆🍆🍆 creating problems ??

I've never had to use lube, but my boyfriend and i recently started having sex and he's just a big guy in general, he's 6'3 or 6'4 so I shouldn't have to explain what's in his pants. but every time we have sex we have to use lube, like alot of it continuaslly or else the sex starts to hurt me. should I not have to use lube ??? if i get used to his size will i be able to stop having to use it? he probably thinks I have the dryest kitty cat ever omg 😓
