Welcome to our forum.
It sounds like you have a wonderful relationship with your new girlfriend; I hope we can help with whatever questions or concerns you may have. Poly is a way of life that not too many people out there understand, so it is great that you have been open to this as a concept.
Have a look around on the site, and post more when you feel the time is right.
Glad to have you aboard,
Love means never having to say, "Put down that meat cleaver!"
