Dimensions of sexual attitudes and treatment expectations and barriers were extracted by factor analysis and subjects were grouped into types by cluster analysis. Five types emerged: the sensation seeker, the sensuous, the anxious, the confident and the abstinent. The majority of men agreed on the importance of sex for the partnership. For the majority of anxious, sensuous and sensation-seeking men, sex was important for self-esteem. Expecting quality of life, enjoyment, self-esteem and hard reliable erections from treatment with phosphodiesterase-5 inhibitors, anxieties for side effects and loss of control, sexual abstinence and desire for an intensive sex life had the strongest impact on the likelihood of use. Men’s sexual attitudes vary considerably and impact reactions to erection difficulties. A typology of five groups was developed, which will contribute to research on and understanding of men’s sexual and treatment-seeking behaviors.

Such a typology might difficulties. Grouping patients by behaviors and contribute to the understanding of men’s coping beliefs has been useful for designing educational mechanisms and treatment-seeking behaviors and facilitate future educational activities.
