Am I gay?

The first time I ever masturbated was age 10 in the shower. It started with the thought of a girl in my neighborhood, but as the years went by I found thoughts weren't enough to get me going. So to get that beautiful rush, the rush just like the first time I masturbated I needed images of girls.As more years went by, images weren't enough and I needed videos of girls.Now, videos of girls still do the job, but something happened today... I masturbated to 2 guys fucking and the feeling I got was more intense than that of girls getting fucked, similar to the first one I had at age 10.Am I gay?
