I know the local FTM support group in my town (in California) is open and welcoming to those still uncertain and questioning, and the group includes people at many different stages of transition and pre-transition, and I'd guess that's true of many similar groups. The best thing would be to find a contact number or email address for your local group and ask them before you go to a meeting. I bet you'll be pleasantly surprised.
And oh, yes, I have heard of New Hampshire. 😉
