Hey! Perks that actually (a) trigger when intended, and aren't bugged out (b) do something actually useful - are quite unusual in Fallout; there's plenty of them that are just a trap for the unwary to waste their slots on.

I'd also nominate the 'lady killer / cherchez la femme' perk as being one of those traps; the vast majority of the enemies you have to kill are male, and certainly all the ones who are difficult. It gives a few interesting dialogue options, but there's more effective perk choices.
