I don't know if this is normal but when I was little I slept with...

my sister and one night I was in her room and it was probably 2am and so I decided to sniff my sisters butt and I did and she farted and i loved it. We used to play a game were I would role on her butt and she would fart and stuff and when I was cold she would act like her farts were from a heater and now I take her underwear and sniff and lick them and Also I have another sister who is a cheerleader and I take her cheer underwear and sniff them after her games and I like the smell of both my sisters farts. Is this normal do I need help? Please comment
