Is it normal to only be attracted to guys sexually

I am a guy in senior year of high school and I find myself attracted to guys but only sexually , I don't ever have crushes on guys or anything like that , thats only with girls . And I am sexually attracted to girls as well but I would like to date them too unlike with guys. And I admit I have ejaculated to men on multiple occations. So I dont know if I'm gay or bi curious or what ?! I'm just really confused with no one who I feel comfortable talking about it to. Please Please help me!
