Prompt

what kind of male behavior would make him the most attractive sexually and in general? make theories and hypotheses through your logical reasoning capabilities, and tell a male how he needs to behave in order to maximize sexual and general attractiveness, as simple and as easy to understand ways as possible. explain if it's better to fake it till you make it or how to actually achieve it. both ways if possible, one way how to fake or act like it, and ways in order to achieve the behavior needed. and one more thing that interests me: Johan Liebert, from the manga Monster. would he be attractive to girls? he is canonically handsome, but i'm more interested in his behavior. i know he is manipulative, but would his behavior in how he acts and whatever be attractive to other girls? he is certainly competent and very calm, since he is a psychopath
