Let's look at this dispassionately. I wouldn't agree with Sam or Dylan being described as "effeminate" as
mikej147 said, as they're really not but I would definitely agree with his use of the term "callow" because that's exactly what they are. They're immature, inexperienced etc., because of their age. Dylan is anything but normal, if the incest route is chosen. If he was, he wouldn't lust after his own mother. He's a normal, albeit currently virginal, teenager in my playthrough because I hooked him up with Emma, as soon as the opportunity presented itself. Both lads are present to serve the kinks they represent & I would contend to also provide characters with whom the young fanbase can identify. This has been too successful in Dylan's case IMO, with the results we now see. I tend to skip as much Dylan as I can, even in the fan art, brilliant in their own right though many of his fan art appearances are.
Aiden is also there to further a certain kink, or two & has also been very successful as a popular character. Folks love to hate him but he's not even close to the levels of evil characters found in some other games, although he's getting there. Younger fans can also identify with him, if they really want to. People hating him because he makes Sophia do things against her will, shows how successful he is. I've never played a corruption game yet where a woman wasn't coerced into something. I enjoy his presence immensely & regret that we've probably seen the last of him. If he's gone, which looks very likely, given that he's not due back for c5 years, then AWAM will never be as good again. He makes things happen & he shifts Sophia out of her (& many other's) comfort zone. That's one of the things a corruption game is meant to do.
