Tough question: There are several things that could probably cause this. This could be a sign of low blood flow to the penis or more likely is related to a psychological cause. For example, if you just are not stimulated by the appearance of your partner or if there are some deep unresolved issues these can surface during sex and effect your erection. Is this the first/only time? See a urologist.
