Me and my Girlfriend have been getting closer and closer to having sex, but because she does not feel ready yet we do things with clothes. Sometimes When we do that I do the "knee thing" A lesbian friend once told me about it years ago and I've only tried it now. Basically pushing her against a wall and rubbing the knee or my leg on her vulva through the fabric.
Can you give advice on how to make it better for her, or does it even feel good? Please tell me, I need advice.
