As someone who only recently ventured out, OK I was dressed as the opportunity presented itself, to meet up with others, I fully understand what it is you are conveying in your description of the evening.
All life was represented there, I wasn't the tallest, the shortest, the one who passed most or least successfully or even cared. Each had their own reasons for being there, non of which were wrong or deserving of criticism. We all contributed to the whole in our own way and in that I found great strength and a determination to move on in my own journey.
Mikell, when you say; "so first time sharing myself to a group....still not out dressed...but i think i would have been comfortable there", I think you hit the nail on the head. I was made to feel so very comfortable. I just felt right. I truly hope you get the opportunity to go dressed as it will be so liberating but be warned, the desire to go again will be ever there. There is no antidote!
