I see this everywhere, all the time, and even here. They're not some kind of special creature that can read your mind. How many times have you read "they can smell it from a mile away", whatever "it" is. Be it insecurity, shame, guilt, neediness, etc... Newsflash, they're just walking pieces of flesh but instead of a dick down there, it's a vagina. They don't have some sort of magical radar that can detect personality flaws without a clear sign that you have them.

Obviously, this doesn't mean that they CAN'T detect these things based on your behavior. But ultimately, if you're putting on an alpha/badboy/badass/whatever-the-fuck-you-want facade, chances are they won't detect shit unless you slip. So don't slip.

Get rid of this fear of, "Oh, if I pretend to be this or that they'll just know it because magic". Women's intuition to the degree that it has been glorified is absolute bullshit. Imagine you see a 6'3 Chad walking around, and he walks and talks to everyone with amazing frame and confidence, yet for all you know he sits in his basement 12 hours a day playing videogames and jacking off to porn (unlikely scenario, I know, but bear with me), you wouldn't even think those things of him, why? Because you've glimpsed his personality for the first time, and that's what you assume his static personality to be. The only people that can "smell" if your insecurities are people that have known you for a while, and in that case it wouldn't even be considered smelling.

So get this bullshit out of your head. Be whoever the fuck you want to be without regard for what these women might smell. Hopefully the only thing they'll smell is the jizz lubricating their nasal cavities after you've dumped a load worthy of praise by Zeus himself.
