my boyfriend has never made me orgasm

he has never made me orgasm.

When he's done, he just says "let's take a shower." He never asks me that am i happy with sex that we just had.

Once we had sex and he finished in 3 minutes... I told him that i had not finished yet. He just said sorry and promised that he will make it better next time.

I know that sex is not the whole thing of being in relationship. But you know I'm bored that I have boyfriend but I still have to masturbate to make myself orgasm.

What should I do?

Thank you in advance
