I am dating someone older than me and am rarely around kids at all. Would anybody be able to tell I am a pedophile? Of course I am non exclusive and attracted to adults as well, but still...
Most pedophiles also get really good at hiding it as they get older too. When I was younger maybe someone could have figured it out due to my adoring of my little cousin, or finding my stories I wrote. Or shows I watched. But, now... I doubt anyone would be able to find out.
