I completely understand why some women don’t want to post face pictures. Thus, I never ask for one. However, if I am choosing between two possible SPs and one has a face picture that I like, I am more likely to go with her than one without a face picture. This is true even if the face picture is incomplete (e.g., just the bottom part of the face). Partly, it just makes me feel a bit more comfortable. Also I do find a cute face to be a turn on.
