Feeling confused...

Hey guys, I could use some help figuring this out. I'm in my early twenties but ever since I was 12 maybe 13 years old, incidents here and there have had me always wondered if I was gay but was always too afraid to find out.I never really had crush on a girl before, even when I was a teen unlike most of my friends who would be going after girls they like. I think I even had a crush on a guy once back in school but didn’t really know what to think of it at the time. I am sometimes attracted to women but only if they’re really attractive but I wouldn’t say I am really infatuated.Whenever I see pictures of men and/or women I find myself checking out the men more than women perhaps even in real life like when I’m out and about, an attractive guy would grab my notice. If I were to ask myself the question ‘can I see myself with a guy?’. I really can’t say for sure but if I have to be honest it would be a 'yes'. Maybe I’m just too scared to admit it. But am I really gay or is this something else?
