Is there any way to delete my "recently watched" on Netflix?

I hate hate hate this feature. What is the point of having this? I live with my family and I would rather them not know everything I watch on Netflix. For example, I love getting piercings so I watched “Modify”, and now my mum thinks I’m obsessed with body “mutilation”. I’d also like to watch some of the movies from the “gay and lesbian” category, but that’s pretty problematical when you have a suspicious family and you’re still in the closet.

PLEASE. Is there a way to disable this or delete the content on it? Why has Netflix not removed this by now…
