Can I stop being gay(my theory)?

I was thinking lately. After watching back to the future it hit me. What if I invented a time traveling delorean. Install the flux capacitor and generate the 1.21 giga wats of electricity. Sending me back to the year 1992(born in 93). I can go back to that point and "pull a Mart McFly" meaning do something to alter the space time continuum. I think its possible. I mean Einstein did offer the theory of relativity and the theory of alternate dimensions. I think gay is gross so why not go back in time or something.
