Laura's playground has a "child forum" but maybe your parents aren't really ready. There is a guy on youtube skylarkeleven who has a set of 3 videos with his mom. Though she seems to have very little trouble with it.
There are a couple books that may be useful: I think "Just Add Hormones" is very short, breezy, easy, unscary book to read. The guy seems very normal. This would reassure your parents, I think. There is also the more serious "Helping Your Transgender Teen" (5 stars). I know you are a bit older, but I am guessing this would still apply. Haven't read this.
