Can't help you with the trans group thing, but hope you can get some info. I search Yahoo and here for groups that meet in my areas.
In your avatar, you look like a friend I had in high school. He has some extra ear piercings that work just fine on him. I'm on middle ground about snake bites. I think it falls into the hipster/Hot Topic era of things. From the time when Hot Topic took over everything. Not all of them, by any means, but that's my first image. I know people who have them and I love them. I like piercings, and think that if you want them, go for it.
