Confused regarding my sexuality! Plzz help

I am a 17 y/o guy who recently installed Grindr and had a few hookups. I also enjoy gay porn a lot.(I also like straight porn but I can’t get hard by lesbian porn or naked girl pics). I am very much attracted to the male body but I would also like to fuck girls and dominate them.however I want men to dominate me too. Romantically I like girls only,and I also had a few crushes. Am I gay or bisexual? I just want to have a normal life,get married have kids but I’m afraid I won’t be able to fuck girls and that scares me! Btw are gay men able to get it up for women? Thanks
