I think I could be biual?

Im a dude, and I have always been attracted to girls. When I was 10 years old, I began to wonder what a girls private part looked like, so I went online, and thus was introduced to internet . Then I had my first when i was watching it one day, and then discovered masturbation. I masturbated steadily to girls for the next year and a half. Then, one day, I learned about ity, and I decided to see if I was one. I was not at all attracted to men. The next day in school, they found my computer history and everyone started to call me gay, so I began to believe it. Now, it is 7 months later, I am 13 years old and I still don't get attracted to men, just women. Recently though, like for the past 2 or 3 days, I have been less attracted to women, then EXTREMELY attracted to women. Its weird. Do you think it could just be the power of suggestion?
