If you have been sexually attracted to a member of the same sex that makes you gay?

I am 14 and I have never felt sexually or emotionally attracted to a male before. I am 100% heterosexual, I know that I am sexually attracted to females. I am sure a person can be attracted to a person of the same sex. And I even had that with a male once before. However, I just don't feel anything romantic or sexual attraction to males. I am sexually and emotionally attracted to females so that makes me 100% straight.
