Compliment her outfit or, better yet, compliment her aims and ambitions.
Girls and independent escorts in London adore witty guys, so why not try to turn her on by displaying your sense of humor? You need to connect with them emotionally and psychologically before indulging in physical contact with them.
However, you must first shower her with emotional and mental intimacy to bring her to that level of intimacy and comfort.
It may not be as great as the other sexual turn-ons for girls on this list, but it works well.
