I would discuss this with your psychiatrist who manages your medications for schizophrenia. It is possible some medications such as anti-androgens or antidepressants could help. Sometimes medications are given for the benefit of their side effects (called "off-label" use). There are a number of medications that have a side effect of decreased libido or erectile dysfunction so it is possible the doctor could find a way to help you here.
