I can relate to that feeling of fear and excitement. It's a good idea to go slow and let the feeling settle before moving on... there are some great threads on here about what some of us have learned and some ways to approach poly in terms of setting yourself up with a foundation that works... you can find them by doing a tag search for "lessons" and "foundations." Other than that it sounds like by identifying as open that you might not yet know the avenue of exploration you want to travel down... is that so? If not and you find that a poly approach as you define it is a better fit then great... as long as the two of you understand what meeting and becoming involved with another person will mean to you in terms of depth and connection or just fun then you are good to go in making a move.
