LGBT sexual talk... Tips, Sugguestions, Anything !?

I’m a fem, and my girlfriend is a stud. This is my first time ever being with a girl all of my 22 years of life. It kinda just happened and here we are. My question is with pleasing a stud. How do I know what I can and cannot do to her. I know some studs don’t like to be touched etc. that’s not the case. I’ve eaten her out and sucked on her breast and everywhere else. But I don’t know if I’m doing a good job. When I was with a man, my ex I knew how to please him. He actions and body language would show me. But with her I don’t know. I wanna do it all, I wanna be nasty . I wanna be her freak. But damn I just don’t know how! And I don’t wanna try things and she say stop or no! Like sometimes she will want me to stop eating her . I need help, She’s the type if I ask, shes not gonna tell me what I can or can’t do to her.
