There are lots of articles but I doubt their real value as subs are as individual as anyone else. Simply put, one size does not fit all. You'll need to listen and explore her views. Maybe ask her what sexy books/films she likes & then talk about what she sees in it (I safely predict it'll be very different from what you took away!) If you want to read a lot of wittering by people who have personal experience and think they know a lot about it, sign up to Fetlife. People write a lot of stuff as if they were authorities and, as long as you bear in mind that they often have an axe to grind about the authenticity of one particular version of BDSM or whatever, you'll find it interesting. And just be aware that some of the stuff on there can be quite unpleasant so try to bear in mind that it is presented as consensual and typically only appeals to a few people.
the number one thing, is communication. talk to her about what she wants, what she is comfortable with, what YOU are comfortable with. she might just be looking for a get together where you just take the lead, as you said. there is no one thing that subs need/want. it's like any sexual partner - everyone has unique tastes.
You can’t truly call yourself peaceful unless you are capable of violence. If you’re not capable of violence, you’re not peaceful. You’re harmless.
Talking? I have learned as a sub that I cannot talk by myself. If Mistress asks me something I give her an honest answer. Or I'm silent.
Mistress had forbidden that I came together with another Mistress or lady. And then she asked me: "To what Mistress are you attracted?"
I gave her an honest answer. I told her that I was attracted to her. She did not accept my answer and pressed for an honest answer.
Then I told her: "Let me give you an honest answer. I do not want you to get upset. I'm very attracted to a black Mistress. I feel she is tough."
Mistress thanked me for my honest answer. And then she had a hard spanking for me with her riding crop. To let me know there would not be a black Mistress.
