During intercourse I fantasize. This makes me feel guilty. But if I don’t I won’t come.

Many people need to withdraw into their own feeling or thoughts to leave the plateau phase and come to a climax. This is called the solo phase of sex. But there are many women who hate to shut out their lover, even if it’s only for a few minutes. For them it makes sex less intimate and spontaneous. If women feel this way they can choose not to enter the solo phase. But they often pay their price: being unable to come. You should do what feels good to you.
