I don't even understand the "boring sex" line. Gale has one of the most elaborate and over-the-top sex scenes in the game. Yes, you can choose "boring" sex instead (and I do), but that doesn't seem to be what the line is referring to. Is it implying he's out of practice or something?
I've wondered if it has something to do with him being monogamous as well? I am not entirely sure where the idea came from Gale is "vanilla" when 1) the weave sex scene is incredibly wild where he essentially triple-teams the player character and 2) he even implies him and Mystra got up to some kinky stuff with her sounding him with weave, like... It doesn't seem factual at all and just a way to be mean to Gale
when in a relationship with him.
Now, that said, Gale gets the *best* Act 3 and the coolest finale out of everyone.
I don't agree with this? Gale only gets a cinematic ending if he opts to kill himself. Otherwise his other endings basically happen off-screen (until the epilogue, if not playing Gale origin, it was legitimately a mystery what happened to him if he chose godhood/wasn't in a relationship with the player).
Even in Act 3, Gale's arc is just finding out more about the Karsite Weave and then making a choice on what to do about the Crown. If the player opts not to kill Gale, he doesn't have much else to do. It feels a little incomplete.
