Although i have "came out" to my mom she keeps telling me it is a phase and I'm to young to determine my sexual origin (I'm 13) in you guys opinion do you think i am to young?
Some know it sooner than others, some "have always known they were different". So it's perfectly possible I guess.
I find it early, but yeah, some find out sooner than others. Also: in my point of view, you aren't "smart' enough to make it into a phase. Don't know how to explain. You'll just have to decide yourself, if you're sure, it will probably be.
