My parents dont know i like Yaoi D:?

Ive been reading and watching Yaoi since i was 14 and i was very careful so my parents wouldn't know. My mom would think it was weird but wouldn't care much but my Dad would seriously think i was messed up. He doesn't like gay or lesbian people because he was raised that way. Im afraid that if he ever found out hed disown me or find it hard to talk to me Q.Q I cant stop being into Yaoi its too difficult, any advise anybody? D:
