Is my family crazy?

My 7 year old brother is a perv.He hits on his mom and two sisters. He flirts with his gramma and random girls. Once when he was 4 he saw a group of teenagers the street and said "Hubba hubba". When he was two he walked in on our great grandmother changing and said oh mama. He loves to say mom have sex with me

my 10 year old sister.She kissed with a boy age five at the McDonald's play place. has pics of the 11 boyfriends she's had in the last year.She gasses and burps like a man but wears dresses and a crapload of makeup

Dad is odd. He is obsessed with Disney. We go twice a year and he is always the most excited. He loves Disney movies. He plans the trip 5 months in advance. We are in the Disney vacation club. He also makes our house Fort Knox. We have 8 security systems, cameras in all rooms of the house except for bedrooms and bathrooms. He has motion lights and more. He takes three fighting classes "just in case". We have 6 safes and 5 guns

Mom is inappropriate. She gasses constantly.she can't go an hour without sticking up the house.We're gotten testing done. Her excuse is "there's something wrong with me". My dads hilarious response is always the same. " they have done every test with a name. They have gone up and down and in and out. They have done everything and all they can find is ur just gross". She talks us like we're her best friends. I'm 13 and she tells me details about her sex life and if constantly telling us dirty jokes
