Bits from the AoW Forum :
Anarch Cassius:
Seduce only works on male units, even when used by a male unit. No male unit in the game posses Seduce by default but it can be given to male hero by forging an item with Seduce. It can also be done with the editor which is where I first discovred it but I figured it would be more likely to be fixed if I showed it could be done in a normal game.
The obvious solution is of course making Seduce affect units of the opposite sex. Yeah it's heterocentric but I really don't think all units should be gay and if they were bi than Seduce would basically become Dominate and Gender would be a meaningless stat.
I can provide a savefile if requested but it easy to test on your own.
Anarch Cassius :
The fact that any unit regardless of gender cannot seduce females but can seduce males is fine? Honestly I think the current setup is quite bizzare and sexist.

Once I was talking to my grandpa while playing AoW1 and fighting some nymphs. All he could hear was "OOH," "Ahhh..." and her death screen "WAhahahoooheee!" a max volumes. He was very confused. :P
