The `Dirrty` singer - who has two-year-old son Max with her husband Jordan Bratman - wants her offspring to grow up understanding that women are allowed to express themselves in a sexual way. She told `Access Hollywood`: "He`s going to grow up in a household where he knows mommy expresses herself artistically and some of that will have to reflect itself sexually too at times. He`s going to learn to respect the fact that women are allowed to express themselves and not feel shameful about their bodies or their sexuality." The 29-year-old beauty - whose new single `Not Myself Tonight` shows the pop star in a number of racy and provocative outfits - claims motherhood would never calm her down because that`s just not what she`s about. She said: "Mama still has to be me. I never claimed to be a cookie-cutter soccer mom. That’s all good for some people. Not for me." Christina recently spoke about how her self-confidence had soared since falling pregnant and she has actually felt more sexual since becoming a mother. She said: "I`m more confident and comfortable in my own skin. I think I`m even a more sexual Christina. I think it`s important that he sees mommy not be ashamed of her sexuality. I mean, he`s two. We`re art collectors, there are a lot of female nudes around the house. Max will be growing up in a house where it`s just the norm... It`s only weird when you shame it."
