There is a film that is simmering on the back burner at NFB called "Hommes à louer", where Rodrigue Jean has interviewed at length male prostitutes in Montreal. The men interviewed say they despise their clients, speaking essentially of doing it to feed drug addictions. In that, they are similar to what most female workers are saying to researchers. I don't know enough documentation or research about what men who buy sex with men or sell it think and say to offer a summary other than cites such as those above. Feminists often tell me they would like to see allied men challenge men who buy women into dialogue about their values.
