I understand what you mean about feeling abandoned, but perhaps you could explain this to him. I have to say the idea of being bound and laying next to my master all night is tooooo hot for words, but then I think he would be more inclined to show a little affection afterwards rather than just send me home - perhaps talking this over with your master would help. As the relationship is quite new, you should make your feelings known and then you can both progress along the same path.
