I dont know what it's my sexuallity

I think that im bisexual, but i like girls more than boys. So i dont know if im lesbian or not. I has always like boys, but when i kiss them i dont feel nothing, but when i kiss a girl a feel something and i like it. I have never imagine my self having sex with a boy cuz i dont like it. I always think in my future having a wife and childrens. I dont know what i like because i fall in love with a person for the feelings and the way that he/she treat me. What do you think?
