I'm concerned about this as well. I chose Tamika on a whim, and I want to make sure it's a good fit. I think it is, I really love it, but I need to hear it from more voices before I'm going to be absolutely certain.
My friends were using it the other night, and it was... interesting. I think, because up until I came out, it was so intimate, for me only... to have it out in the world is kinda strange. But nice, definitely nice.
And it sure beats the hell out of my birth name, which is like a punch to the stomach every time I hear it.
