Getting on gales good side is blisteringly easy. Seriously, that man goes from zero to best bud at the speed of a few days just by doing run of the mil hero stuff that you were probably going to do anyways, unless you are playing as a sociopath that gets a kick out of torturing refugees and murdering children. Matter of fact, just running around like some sort of benevolent exp hoarding loot goblin (like the overwhelming majority of people seem to do in almost every RPG since the beginning of time.) will be more than enough....
Very well said!
I do not worry that much about more sex than romance (we can hope that for Lae'sel and Astarion sex is the beginning of the romance) but agree that for others some flirtation first would not hurt. And this is mu major concern: may be there was some flirting but the scenes were eaten up and lost due to dialog system?
