Already implemented, and this'n belongs in the suggestions/ideas board, not the species board.

Almost all of the above will be implemented, but I'm closing this topic for being too broad. When possible, try to use the suggestions board for specific, actionable tasks / suggestions.

Already possible in the advanced editor.

Already in the game. The random generator doesn't differentiate between mherms and fherms yet, but it DOES already have the herm genitals you're describing (essentially a vagina with a penis for a clit).

I am... shocked to see that this is so popular. Interesting.
