I get to find a girlfriend!

Soo, I am a Bisexual woman and have had some good and bad experiences in my younger years with women but never an actual real relationship, I’m 29 now. However I am now with a male, been together 8 years, and we have two children together.

Entering my 30s has been good for my sex drive and the conversations with my SO have included how much a third could bring to our relationship. So now I am trying to figure out how to even meet new people? Let alone, a woman who would even be interested in this type of relationship. Any advice?
