Looking for a younger lady for an unconventional relationship

I would like to meet a younger lady for a long-term relationship. You might be single, or perhaps in the process of leaving someone (without children). I am 41 years old, living a normal, stable life. But I am looking for something that might shock you: a woman who would be intrigued by the idea that her future guy would be okay with her occasionally going out on a date with another guy (if she meets one), while her guy would still be fully loyal to her. If you are interested in such a relationship, write to me, and I will explain more.
