Vasectomy vs female birth control

How can I be the one to accept the fact that I am the one whose body has to undergo constant treatment to avoid pregnancy through various options (ie. birth control, iud, etc.) while males don't even consider an alternative when I'm already the one who goes through physical pain each month just by being a woman. Is it an unreasonable request for long term/life long male partners to consider one option that takes away another unfortunate option for a female? Why is there such a huge discrepancy between males and females? Why is it innately harder to be a woman than a man? Should male contraception be equally considered as an option for couples who don’t want to have children?
