Am i gay? I started liking boys as soon as I went into puberty

Hello, my name is Scott and I am a 14 year old male. Recently some changes have been  happening and I have a few questions im hoping you can answer. All my life I've liked girls and infact dated a few myself, (although none lasted long). Ever since I started liking people it was always girls I preferred and couldn't even imagine kissing a male. but recently I have started going through puberty. And im starting to like boys... I still however like females, I get nervous around them or butterflies in my stomach when im near them. (Sorry if this is personal but I think its needed to explain here) I of course have masturbated to porn, like im sure the rest of you, and I used to prefer females. but recently I switched to gay porn and I much prefer it... it feels... right. I was told by my good friend that maybe since I was always told at a young age by my parents and everyone else that boy liking girls and girls liking boys was correct. But I started puberty and well im starting to have a preference to men, maybe since my hormones are telling me what I actually prefer? It started off in the boys locker room during P.E, and I saw the shirtless boys and I thought they were hot and stuff... but its grown. Im starting to be attracted to men over women. To elaborate on this, as I already stated I like girls and boys, and feel like I could be with each. But im slowly drifting towards men. Im starting to have crushes on boys and dreams about certain things with boys... What I want to know is, am I gay? I like men, but I also like women, but im slowly liking men more. Maybe because of puberty? Idk.. maybe just a phase? Please it would be appreciated if I got your opinion... I want to know if I am gay, or an explanation as to why im starting to like men. Thank you for taking the time to read this.
