AIO for thinking my partner is a pussy

that sounded rlly rude, but it’s the truth. my partner is too ‘scared’ to get protection for us (i’ve got it before, but im trying to save for important things and they’re pretty expensive near me), which really frustrates me because week after week he’s promised he’ll get them, but never ever does. idk what it is that makes him not want to buy it. it’s not like he wants to get me pregnant bc we are both petrified of that. what should i say to him? i don’t want to be rude to his face but i also want him to know that im sick of this?
