Speaking for myself, of course, I think there are several things at play: firstly, we are socialized as female (generally), and therefore not generally accustomed to making the first move. Secondly, it can be dangerous to make a move when you are a butch. Lastly, I have no interest in straight women, so yeah, if I assume/think someone is straight, I keep my energy to myself.

Overall, I do think that knowing that the opening is there, so to speak, allows me to feel comfortable expressing interest. No opening, no interest.
