I tried so hard to be straight, but I learned that if you have to doubt yourself, you are most likely gay.
I don't know what type of person you are, but from my own experience, there'll be a lot of denial. At some points for me, I was watching gay porn and still trying to tell myself I was straight. The only thing that can fix it all is time. Eventually, if you find yourself to be gay, you'll be cool with it. It won't be easy, and it won't happen in a week.
