^^ It's like the guy who is happily in a relationship. His body language doesn't give off signals that he's looking for someone. He's cool, calm, collected, serene in his own thought (being in love). He's exhibiting a reserve of 'confidence' and women notice this. And this piques her interest. They notice he isn't - HUNGRY - like every other guy around her looking around, fidgeting, trying to act cute or macho (or creepy). This is what you want to emulate. This is the state of being 'alpha'.
As far as myself and my own attraction state towards women as I change into andro-fem, I can't say I have experience with that yet. I'm actually enjoying my new found evisceration of my libido from HRT - lol. No seriously, I'm really in a renewed discover-myself state. I'm like my own lab experiment being the subject and the cis world my social medium. Testing if the changes I'm working on is really right for me. If yes, then confidence projects from there. So I haven't been active in pursuing women as of late. But when I do, the same music applies, with perhaps some lesbian notes and embellishments.
