Questioning my sexuality?

I am really turned on by girls and I know I'm not gay but I think I'm might be bisexual. I have looked at gay porn somewhat, I am not turned off by sex with another guy, I had a sexual relationship with a friend for two and a half years. My mom accepted me but I'm not sure about my dad and my grandmothers I don't think would accept me. am really turned on by girls and I know I'm not gay but I think I'm might be bisexual. I have looked at gay porn a little but I fantasize about sex with another guy though not as much as girls. I am not turned off by sex with another guy, I had a sexual relationship with a friend for two and a half years. I could see myself with another guy as well as a girl. I'm more effeminate than most guys and make friends easier with girls. I have taken quizzes and tests most of which say I'm bisexual. A gay male friend said I was bisexual, a lesbian friend said not to worry, and an adult I trust said not to label myself. can someone help me figure out what my sexuality is?
