At a specialized hospital for urinary and anal treatments, most patients are men. Some seem to mistake the clinic for a brothel. Trying to understand these patients' feelings, I kindly accommodate them. Most end up ejaculating, and I'm very familiar with that sensation. Because I'm a masochist, I often sense that many patients feel compelled to examine my anus or roughly rape me. When I'm alone, I constantly find myself thinking about such things.
