Welcome to our forum.
Things are usually scarier (as well as more exciting) in the beginning of a poly relationship. Just take it in small steps, don't rush yourself. And do lots and lots of communication (always practicing to get better at both telling and listening).
You will certainly be able to get some good advice here; just post any thoughts, questions, or concerns that you have. Explore the various threads and see what interests you. There is a search and a tag search feature as well.
I am hoping for the very best for you in your new poly relationship. It sounds like a very positive one.
Glad you could join us.
Love means never having to say, "Put down that meat cleaver!"
