When I was 14 probably. I actually almost started DIY'ing a long, LONG, time ago. Basically as soon as I realized AMAB's could be femme I wanted to be that. But I was too scared (and still am kinda scared, but I'm dont being afraid of what I want). Really the only reason I've waited so long was societal and family pressure. Being pressured on being a straight male with a normal marriage, house in the suburbs, is easy socially but mentally fucked me up. I finally snapped recently once I realized I can just say "no" and do what I want.
