Lesbian?

I prefer to watch lesbian porn over any other it's just easier to picture me as one of the girls and kind of like imagining the feeling you know I mean does this mean I'm a lesbian because I do find guys attractive and I could never really see myself dating a girl simply because I don't find that to be something I enjoy like I love a guy that's taller then me and deep voices are amazing and when they are muscular my god but I don't understand the whole enjoying lesbian porn thing  I especially love humor in guys but with girls it's like being friends is all I would ever do
