One of the areas of Satanist (and general) interest that seems very appealing to me is that of 'influencing others into doing what you want.' Now, being one of the few who have no read the Satanic Witch (

I know, for shame!), and thus knowing not nearly enough about the topic in a Satanist sense, I've come for some advice.
The issue, in my case, is that I'm aware I'm doing something wrong with my body language, which while grabs the attention of some girls/ people, it's attracting the wrong kind of people. I'm not sure if it's a mix of physical appearence (I'm among those who have a 'sweet look') and the way I do things like sitting, reading or think/ daydream, or something else? The problem is, then, that I attract this kind of people who come to me having a preconceived idea of me (things like 'he looks like a good christian boy') and when they see I'm not who they thought I was their attitude change quite fast (it's frustating as I'm not interested in that kind of crowd). So what can a person do to, using body language, attract people who fit better into the choices they've made? What sort of ways can a person use to project a more dark aura (or white, if needed) to others?
I know that is hard to give advice when no one here knows me in real-life, but some pointers would be appreciate it.
