The pictures of me playing with dolls and wearing dresses, should have known...
Needs a Better Title -- this one's awful. It's a common stock phrase that goes along with the trope, but it's misleadingly broad. I just suck at titles and couldn't think of anything better. Also, this is a pretty lousy writeup. Oh well, I hope it makes sense. Anyway, this is the idea that gay characters manifest their "difference" in childhood, long before they could be said to have a sexuality as such, by having interests and pastimes more associated with the opposite gender. Lesbians probably spent their childhoods climbing trees and refusing to play with dolls, while gay guys are likely to have eschewed sports in favor of playing dress-up. This in turn means that the character themself and/or the people around them may suspect that they're not straight (won't be straight?) well before they actually reach puberty (which is where the "always knew I was different" thing comes in). Ties into Butch Lesbian and Camp Gay, as well as the whole "gay = transgender" confusion (which I know has been YKTTW'd before, but apparently wasn't launched). It often is Truth in Television, but also may carry the implication that (a) Straight Gays and Lipstick Lesbians don't exist and (b) any child who doesn't conform properly to gender roles is probably going to grow up to be gay.

Jodie: Mom, I should be a woman. I've always felt like a woman. Mom, remember when I was four years old, and it was Christmas, and you gave me and Danny those little plastic shaving kits, remember? Remember how Danny took that little plastic razor and started to shave his face...I shaved my legs, ma. It was obvious even then.Web Original
