What's intrinsically wrong with incest itself? Abuse and power imbalances are clearly badong and evil, and inbreeding is bad news for everybody involved. But as long as the former doesn't exist and the latter is avoided (or is not an issue because homo), what's wrong with two responsive and consenting people loving each other?
Of course the involved being children or teenagers detracts from the 'responsible' part, but that's an issue with all instances of love before adulthood.
