oO I never used potion, and I aways get the ones I want at the same day using only one action, even the stubborn uncivilezed prude ones... kinda weird btw.
>entrancement spell(never noticed difference using it or not)>go to garden>alternate between chat, hands, light kiss, comb hair, hug>if it gets to near 3 turns to finish and its still barely half bar, move to bedroom>chat>request intimacy... sometimes is even possible to throw in a teach or two.
if there is gold to spare, going to streets is faster to build up mood.
I kinda think it needs more balance too.
