Straight but so confused?

I literally adore guys, their so yummy in my head but I'm also afraid of turing towards women. Im just not settled in yet and idk why. Im afraid that I will turn somehow in the future cos I'm kinda easily influenced a little. So what do I do? Am I straight completly? And Please dont suggesst experimenting cos just picturing kissing a girl makes me feel a little sick in the stomache. I'm not here to offend, just being honest. I'm almost 15 btw
