Confused sexuality

Im straight .. I have a boyfriend for over a year now and I love him and his body and I love guys.. But back in elementary school me and this girl would sneak off to the bathroom and we would kiss and touch each other.. (I was a very horny child lol) butttt sometimes I still have sexual dreams about girls ... Even in middle school I would occasionally (and I don't like to admit this ) look at lesbian porn and it would turn me on... But idk .. I'm confused.. I am so soo in love my with boyfriend.. I even had a dream about a girl a couple nights ago.. Any one have thoughts on this ??
