Scientifically speaking,

Would a woman with anorexia nervosa make a suitable mate?

On the one hand, atrophy of cardiac muscle would give her a reduced cardiac output, so she might not be that great in bed (sex life is important)
On the other hand, her amenorrhea would mean that I would not have to use condoms to prevent pregnancy (save $$$ in the long run)

So in conclusion, how would a scientifically-oriented person do the cost/benefit analysis in this situation?
