This is still in Early Access and Larian said this might last a year. The romance that we have currently available in the game is just a taste to give us an idea of what they are doing. That's why when your character has sex it says "Under Construction" because they are still working on it. If you feel the romance is rushed, keep in mind that the game is not finished yet. When you got the Early Access, it tells you to give Larian feedback so they know what they should add or work on and that's what these forums are for.
I agree with you on this. I think the romance we got in game was a test run to get some feedback on how we want it to develop, how well it plays out, bugs, etc... We are just test-running different parts of the game even if it feels like a cohesive piece it could all change by the time the game releases. Combat, party interactions, exploration, romance, etc.. all is being evaluated. So everyone into romances should give constructive feedback on what you would like to see more or less off.
