Oh yeah I get fanfics aren't about their entire life and all, but I think a lot of fans get their ideas from them. Like, per example, Sungmin being a perpetual bottom because he looks more feminine or because he's smaller. Idiotic, really. It's true that in some homosexual (and in some heterosexual) relationships there's a more dominating figure but isn't always the case. What would the fun if you are always being dominated by the one you love? It's all about reciprocity, really.
