"For me, it is a choice," Nixon told the Times of her sexual orientation. "I understand that for many people it's not, but for me it's a choice, and you don't get to define my gayness for me.
"I say it doesn't matter if we flew here or we swam here. It matters that we are here and we are one group and let us stop trying to make a litmus test for who is considered gay and who is not."
Nixon, 45, is currently engaged to longtime partner Christine Marinoni, but was previously linked to her old college sweetheart, Daniel Mozes, before the pair split in 2003.
