What makes my face so masculine? (Photo)

I am a girl and have often been asked if I was a man or transsexual and it's ruining my self-esteem and happiness. I am trying to find what is causing this and correct it, I want to look like a normal feminine woman. I have already done a rhinoplasty a few years ago because my nose used to be bigger, although I still think it is too big, but I'm not sure if that's the problem. My jaw or chin appears to be the main problem but I feel like it's not the only problem. What could help?
