As it stands, it's possible to take one of the FO3 seduction perks (Black Widow/Lady Killer) and a FNV seduction perk (Confirmed Bachelor/Cherchez La Femme).
There's two questions here: 1) Does it make sense to allow the player to take both of these? 'Confirmed Bachelor' would seem to be a contradiction with 'Lady Killer', for example; 2) Is the subsequent +10% damage bonus to EVERY human character too powerful?
A few things, one Black Widow, Lady Killer, Confirmed Bachelor and Cherchez La Femme are all in vanilla New Vegas and there is nothing preventing you from taking both seduction perks in vanilla NV. Two, to me taking both seduction perks is making your character explicitly bisexual. Three, I don't think it is too powerful. Using two perks for a 10% damage increase is a fair trade to me.
I feel like delta532 does. It is the players prerogative to choose what ever perks they feel fit, to create whatever character they want. If you take both perks i feel your character would be bisexual.
I don't feel that the damage buff is a big deal. If you take both perks, you deal +10% more damage to EVERYONE as opposed to the Lady Killer Perk which (By itself) only allows you to deal +10% damage to women. And +10% damage is not that big of a deal, it is the equivalent (If I'm not mistaken) of your character flying high on psycho the whole time.
*EDIT If you feel that the damage buff is unnecessary, it can be easily changed in the GECK.
