If you are born female, you often say "Oh my god!" Really, because there is a common hate towards women around the world. There are two sexes in nature but have a lot of differences between the sexes. Most of the sources of these differences are based on social norms. I think that being a woman is very difficult and there are two reasons for this.
Another reason is commodification of women's bodies as sexual objects. Men see as the superior gender themselves and they give priority to their sexual needs. Therefore femininity is equal to sexuality from the perspective of men. One of the other factor is necessity of proving masculinity. The masculinity road goes to the needs of the female body. Women have the right to reject but men also don't accept. So, this situation leads to prioritize murders and rapes. In other words, men's sexual desires complicate the lives of women.
To summarize with mainly seen as exual object and patriarchal hierarchy has a negative impact on women's lives. But there are many more not mentioned difficulties. I can definitely say that it's not easy being a woman.
