Am i gay?

I am 18 guy and i am really confused... it all started when i was 16 i watched some tv and saw some guys kissing and i noticed that i was exremly atracted to it... and that it got me hard.. so i wonderd if i was gay... so i started watching gay porn... and i liked it i masterbated to it.. but i never orgsam to it cause it feels wierd...so sometimes i would watch gay porn, download hot guys pictures...and then it stoped for a while... until by best friend came to sleep over and while he was taking his clothes off i watched him and i could feel that i was getting really hard so we went to sleep and i masterbated thinking about him... wanting him to sleep with me so i orgsamed and it felt really good.. but i lost intrest in him and i was like wtf....and for few days i would masterbate thinking of him...and now i would time to time go watch gay porn... i noticed when i fantasise about guys that my penis becomes alot sensetive and bigger then usually when i think about girls... it feels to good...the reason is why i am confused is cause i dont want to be with a guy.. i find girls hot.. and i want to have kids with a girl..but when i am horny i have cravings to be with a guy.... am i gay?
