Fics like A Fine and Jagged Line (that we keep crossing)

Half a year after the Netherbrain is defeated, Gale has a problem that only Astarion can help with. The wizard has miraculously met just the right woman for him, but after decades of purely non-corporeal delights he's rubbish in bed, and desperately needs Astarion's expertise to save his new relationship. From where Astarion stands, the plan has no downsides: there's no way giving sex lessons to his kind, generous, inventive, and very attractive friend can lead to the vampire catching feelings.
