Alec's criteria for submissives are much more loosely held than his criteria for victims, and have changed more over the years as his social life evolves and as Isabelle unfortunately becomes the person he would consider his One True SubmissiveTM. Alec's initial interest is usually in people who are dissatisfied in their current relationships, who are younger and less experienced than him, often those who have some sort of Societally Inappropriate characteristic (feminine men, mentally ill women, anyone isolated)...basically, people he thinks he can lead around by the nose.

Of course, Alec is willing to take on much more assertive or experienced submissives if they meet other points of interest for him. He has two physical types he's interested in: elegant, sophisticated-looking individuals with long dark hair; and people who look as much like Isabelle as possible. He also has a need for interesting conversation for a relationship to have any staying power, and he favors cynics, artists, and academics.

To be sexually compatible with Alec is easier than you might think, because the slut sleeps with so many people that if he's not getting it from one partner he's definitely getting it from somewhere else. All he really needs is for his sexual partners to be willing to indulge at least one of his particular sexual fixations, which can be as extreme as his sadomasochism or as relatively vanilla as crossdressing or his passionate love for eating people out. He does not, however, like brats as submissives...although he'll happily take them as victims.
