Sorry, but you do come across as so many people do where poly is ALL about you. What if you meet a wonderful woman, but she wants alone time with both of you? Would you pass because of that?
What you really want is a woman who is mostly into women, but open to men. I'm like that, and would appreciate not having to be around your boyfriend much. But he would also surely sense that I'm not that into him. He may or may not like that, in the long run, knowing I'm only in bed with him to be nice.
