The rule is simple in Poland, when you are a woman marrying a guy, you take his last name.
That's not correct although you are right about rules being simple. Whenever you marry, whatever sex you are you have three options:
Stay with your name
Get a double name with hyphen in between
Your partner's last name
Simple as that.
Women usually take the husband's name however if they are professionals or like their maiden name they choose the double name option. Men take women's name usually only if their own is silly.
Very, very rarely the partners stay with different names.
