Black Widow (Fallout 3)

Black Widow is a perk for female player characters $$

Effects
+10% damage against male opponents and additional dialogue options with certain male characters.

Additional dialogue options

 * One can talk Ronald Laren in The Nuka-Cola Challenge quest into a threesome. He then runs to the factory himself. He always ends up dead just inside the factory door if the player character does this.
 * One can talk Mister Burke in Megaton into paying double to do the job, or giving up on the bomb entirely.
 * One can talk Karl into giving up the password to Ian West's room during the Blood Ties quest.
 * One can talk The Mechanist into ending the battle with his nemesis, the AntAgonizer. The Lone Wanderer also gets his costume.
 * One can talk Dukov out of his key without paying for it during the quest You Gotta Shoot 'Em in the Head.
 * One can talk with Defender Morrill at the beginning of Operation: Anchorage, so the Lone Wanderer can come through after the elevator, though this is only for the flavor effect, as they will let you in without the perk anyway.
 * One can use this perk on Defender Sibley in the beginning of the Operation: Anchorage quest-line, where he will lead the player to Protector McGraw without the aggression. He still turns on the player at the end, though.
 * One can convince Ramsey into selling slaves to the player during the quest Into The Pitt.
 * One can convince Wernher to give them 120 5.56mm Rounds, should one decide to side with the slaves in the quest Free Labor.
 * Alternatively, if the player sides with Ashur, they can convince Werhner to leave instead of killing him.
 * One can use this perk on Paulson when he is first encountered. He will tell the Lone Wanderer why he wants revenge.
