I'm kind of with Arne on this score - In terms of males, I'd only really personally consider Gale as a long-term personal option (I'd probably indulge Wyll for a fling, maybe a FwB situation, but I wouldn't really consider him for anything long term. I'd tumble Astarion just for the experience of it, but it'd probably be a 'try-it-once' kind of deal). In terms of the females, they both rub me the wrong way on far too many points for me to ever consider sharing a bed with either them under more or less any circumstance. That's just me though, the player.... I tend to drop into the headspace of my characters when I play as them, and they each have quite varied and different tastes to me.
