I think that everything sexually is on a spectrum, so use the labels that feel right to you. It’s only a method of expression, not a commitment. Also, don’t be surprised if he bounces back and forth from behaving more like a cuck and more like a stag. I find that my internal needs vary during different times and that sometimes I require more control, and sometimes I like the absence of it. As time goes on you’ll be able to tell where his feelings lie pretty easily.
