"It took me a really, really long time to finally get to the point where I was like, 'Oh, I'm gay'," she explained. "I never really was ready to carve out that path for myself, even though, looking back, I always knew that my relationships with men weren't satisfying in that wholehearted way that I wanted them to be. 

"I wouldn't change it because it's really made me adore that part and really cherish it."
