You're not three quarters as clever as you think you are being. While some sex chromosome anomalies leave the individual sterile, others do not. Moreover, even if individuals are in reproduction this does not mean that the individuals are polar opposites. Many plants are fertile hermaphrodites, while others are single sex, and there's an argument that other species have more than two sexes. Indeed, I recall a lesson in a population genetics class in college about a plant with many many sexes, any two of which can reproduce... I thought it was clover or lavender, but unfortunately cannot find a citation to substantiate that. Of course humans aren't plants, but they simply serve as an example of how complex seemingly simple systems really are.
