There is one fansite I know which is devoted to love/attraction of cartoon characters. There is a page in which they can see a long list which shows people's cartoon crushes with explanations, which the site refers to as "harems". All users are free to create their own "harem" page listing their favorite cartoon guys/girls.
Many of the harems and members on that site's forum are females who talk about their favorite animated guys(mainly anime), but there are males as well. In fact, it's one of the friendliest communities I've ever known.
Here's the link... and don't let the name fool you, it's for all ages.
(I really should become active there again... I actually have an old harem there, which was before I fell in love with Frankie...)
