Is it normal that i dont trust male teachers

Well when i was in primary school one of my male teachers was a pheadophile, (he is currently in prison) and when i was in primary school the sad thing was is that he was one of my favourite teachers (which when i found out was and still is really creepy!) and because of this i now don't trust male teachers at my secondry school and i always think that they are pheadophiles and im scared to go into a room with just me and them in it in case they do something. Is this normal, or is there a name or thing for this?
