Thoughts on why we have male and female

Why have male and female?

Thinking about evolution: Why have male and female in advanced species?

There seems to be advantage to mixing genes when creating following generations -- that explains having sex before having children. But why not be hermaphrodite? Why not have both male and female sex organs in all members of the species, and simply trade sperm both ways when "in heat" time comes? This would seem to be a simpler way of handing this mixing genes issue.

Why having male and female works well is a mystery I don't have an answer for.
