“Why does he do it?” you ask. Well, real life relationships are risky. They can bring fulfillment, but they can also bring humiliation. Comparatively, porn lets your boyfriend swap uncertainty for a virtual world that's predictable and controllable.

YES! You believe you have identified a “cause” for your boyfriend's disinterest in real world sex, but his interest in porn is more likely to be a symptom of your mutual failure to find a constructive way of addressing your differences without damaging each other.

It sounds like neither of you feels appreciated and you are clearly no longer willing to discuss your grievances in a way that makes both of you feel good about yourselves.

Whether sex amounts to loving snuggling or rampant sex, physical intimacy is a fairly accurate barometer of the health of any relationship.

When intimacy dies, it is generally because one or both parties are feeling angry, hurt or resentful.

Maybe after being made to feel inadequate about his sex drive, your boyfriend has discovered that he can keep an erection with “eager-to-please” eye candy more easily than he can with a woman who has a tendency to be brittle and hostile. It is your behaviour, as well as his, that needs addressing.

Although you have every right to feel aggrieved, your being right does not automatically make him wrong.
