Yep! There is a Large weiner support group called LPSG. My husband told me about it. I'm not exactly sure why he knows about it seeing how Mr. Johnson isn't exactly large. He sent me the link, so I took a look. When I looked through a few of the pictures my mind was blown. Large doesn't even BEGIN to describe some of these men.
My face was a little like this the ENTIRE time.
I'm not sure if I can link the actual suppot website, but I'll try in the comments. Or you can just google LPSG.
I made an account I hope we can all use.
