Am I gay for doing gay things?

I am 18, throughout my life I have been trying to find the right girl and I have went through 2 girlfriends in my teenage life. Believe me I love women I used to be attracted to them. I love their figure, breast you name it I was crazy about them. But I had my share of male stuff too. I have done gay things before I was even really a teenager. Age 6 I exchanged tongue with this other boy for about 5 seconds. I just felt like doing it. Age 12 I slept over a kids house and while we were sleeping he was touching me between the legs and I didn't do anything because I enjoyed it. Also I used hetero porn alongside with gay porn. But those days are over. I have been unable to function heterosexually for 6 months. I don't know if I am gonna stay this way forever now. But I am afraid when I go to college if I do something crazy with another dude I am gonna like it and then forget about women entirely. So overall I am scared of my sexuality. I just can't believe in two men loving each other. Can I go back to my straight side.........FOREVER
