Ohhh I Luv a Kryton thread.
Makes me feel kinda "normal"
So many people commenting seem to have seized on the term 'Power Women' and gone off on a righteous sexism tangent, completely missing the OP's point. As the OP suggests - Power Women / Power Men, makes no difference. Confidence in conversing with alpha-persons is the issue, made worse by the fact that talking to females can be an even more difficult thing, especially when you like them, which I can relate to.
Though quite why the OP is into this sort of alpha-female person, I don't know. It would appear they probably wouldn't suit him, if so difficult to approach in the first place.
When talking to anyone new, the knack is to quickly find common ground.
This would be easy if one were vaguely normal.
I live on my own in a house with a family of 10 bikes. My career consists of looking at plants in the Arctic and processing data. Not too sure with whom I'd have common ground (female or male). Hence, I can relate to this.
