What do girls think is sexy or a turn on in the bedroom?

i dont necessarilly mean romantic, but physical. My gf best friend said she has been saying how sex with me is boring and not exciting. She said I dont make her feel like a woman and even said she will soon start cheating behind my back with someone who isnt such a "pussy". she also said it has to be natural and shopuldnt have to walk me through it. Seriously I want to satisfy her the way she satisfys me. Tell me some fantasies that get girls all worked up. thanks
