Many men with erectile dysfunction or
premature ejaculation are interested in porn because it's non-demand. They don't have to worry about being embarrassed with their lack of ability to become erect. A man who's impotent isn't necessarily asexual, but he may be uninterested in sex with a partner due to fears of failure and inadequacy. He may also be able to get an erection, or at least more of one, with pornography than with a real person for these reasons. Fear and
anxiety make both PE and ED worse, and are a vicious circle. Again, that doesn't exist with a magazine. Erotic materials allow him to be sexual without those fears. And yes, many impotent men can
ejaculate. Counseling may help this, or it may not. It depends on if his impotence is based on physical reasons, and if he can (and is willing to) change those physical things.<P>Group sex is a COMMON male fantasy, so there's nothing particularly strange in him looking at those particular situations in his erotica. He may also feel that his inadequacies wouldn't be so obvious in a group situation, and that his parter would be satisfied regardless of his problem.
