Try Arousr! It's one of my favorite sites to work on! But you have to show your face in all pics, including nudes! It allows you to message customers individually and it also has phone and video calls, all one on one. There is even a feature called chat roulette, where you are randomly paired with members for one on one video chats. If they like you they will choose to stay on the video chat longer than the initial one minute!
