I need help...Am I gay?

Okay, I really don't want top be gay, I believe in Jesus and God, and the bible says not to be, and I pray like ALL the time for them to help me but yeah... I am like fasicinated with women and I dont like them, but since I have "questioned" myself, I keep imaging things, it makes me feel all gross, but I still can not tell if I like it, and I used to like guys until like the middle of 8th grade, but I haven't liked a guy since then(I am going to be a sophmore) and I really really do NOT want to be a . Ewww!!! It makes my stomach hurt thinling about it, but I need to know that there is some hope.
