I agree with u ma@mrs ayodeji, also talk to ur husband concerning his brother, he should stop him from visiting ur house cos he's a bad influence on kids and also to protect ur girls from being molested sexually.

Talk to him, let him know he shouldn't watch it as a child of God. Tell him they are acting and their purpose is to distract ppl from their dream, also sex is only meant for married ppl, anyone who is not married and is sexually active is a sin. Just be open to him...pray with him and keep praying for him. Dont get tired of admonishing him.
