Well the easy solution is the give the romance and then add a whore house to every town for those that just need to bang something.
I also would note that in many romances the 'sex scene' ends up being the WIN for the whole romance subquest. It's like that was the goal and now that you have it the romance is basically over. I did love how in BG2 (comparing them again) the romance continued into the ToB expansion, even having one romance give birth to your child.
I know it's not what the game is about, but I am anxious to see what's done in DOS2. DOS1 was a terrible disappointment to me. I made a couple, but apparently couldn't get the dialog right during conversations and at the end one wanted a romance and the other said 'see ya later' and left.
