Child sexual abuse

Today i saw a programme on child abuse.
i thot abt my childhood days..
bt i jst want to confess this one as its killin me inside.

my cousin is of my age, he my me to sleep in room whn we were in 7th std.
i removed his clothes while he ws asleep n he saw me :(
we hv neva tokd abt it ever. bt its hard fr me to face him n i fear he might tel my family membrs :(
i cant confess it to anybody never :(((
i m really guilty fr it.
