Well- your post is definitely interesting! Not sure if you will find what you are looking for, but it's cool that you are trying. Unfortunately, you are in the majority (couple desiring a female) so you have a lot of competition. I identify as a single woman and I date couples. I like lots of relationships though, so someone like me would never be willing to "settle down" with a couple exclusively.
The key to life is in being fully engaged and peacefully detached simultaneously and authentically in each moment.
