Looking for a younger lady in NY for an unusual relationship

I am looking for a younger lady in NY for a stable relationship. Maybe you are a single lady, or maybe you are in the process of leaving someone (with no children). I am 41 years old and well established in life. I am looking for something that will shock you: a woman who would be intrigued by the fact that her future boyfriend would be okay with her going out on a date with another guy (if she meets one), but her boyfriend would still be fully loyal to her. If this type of relationship interests you, please write and I will explain more.
