Ok, I had to Google what "your kind" is all about.
When I was your age I was in to....well, nevermind.. I was "preppy"...anyway... I think alot has to do with your age, and "finding your own identity" but at the same time is what you are doing Godly? What type of example are you setting for others?
And yes.. you should tell your mother. IF you don't want to I am sure there are members here who will.
