When 女同性恋 或者 gay people get married, whose surname is changed?

In homosexual relationships there is usually a "guy" and "girl" (The "guy" is the most masculine one and the "girl" is the most feminine one) I would have to assume that the "girl" gives up the last name. If not then it would be whoever wants to give up their last name.

I believe its the same as heterosexual couples.
Unless they want to keep their names.

It's just the same way with regular couples the person who proposed to you, 你 usually take their last name =]
That's how I think it is unless the other person wants to keep the name.

I think they can choose whose last name they want to keep :)
