Does this mean I'm gay? Please help?

Hey, I'm a boy and I was wondering if this means in gay. I alwys fantasize and dream of doing sexual and physical things with cute boys and fantasize about grabbin their bum and humping a cute boy with jeans on. I alwys wana cuddle with an attractive boy and f***k a boy and tap his bum in a hot lightly way. I have had feelings for boy and alwys wana mess around but because I bottle this up and feel this way I have an attitude towards most guys thinkin their against me. Advice? Help? Thnks. Oh btw I'm 16.
