Red flag, if she is not affectionate within a month, move on. She may be jaded in some way. It won't change until her sexual peak around 36. Non-affectionate people are often not confident in themselves and this will reflect in more ways down the line as you get to know her. Non-affectionate people do not couple well with affectionate people. Voice your needs and if she doesn't improve, move on to a more affectionate girl who fits your neeeds, better. Best of luck.
