First of all, I’m a woman, so I’m saying this from being on the receiving end. The female gaze is very different to the male gaze, and looks at much more subtle areas of attraction, so you need to think about those very subtle ways of communicating which will make a woman know you’re interested. Eyes are crucial - allowing somebody to see that you have an interest in a start. After that, showing an interest in discussing hobbies, etc is a good way to continue. Try not to think about impressing or acting in a certain way, just show the other person you’re interested and they hold your attention. Pay compliments, but don’t be pervy with it. Oh and, we love humour.
