Is it normal like arse and pussy scent?

It just drive me crazy, I love the smell of pussy and womans arse, I've been with a girl for 4 years, and never told her this "weird" fetish I have... I can't find like porn movies with this content, only few... Is it normal to be addicted on pussy and arse scent? Any girl between 20-25 has the same fetish? I'd love to know a girl like me to explore this unusal taste...
