Quest progression...
From glancing through the thread I see that one should be able to reject certain characters (stop amorous advances, etc), yet still have the ability to advance the main quest. I have found this not to be the case.
I was originally playing as the playboy and not being selective about my advances. But after witnessing the behavior of Luna (who easily fits the diagnosis of Antisocial Personality Disorder*) I really didn't want to continue with her seduction, but in stopping I am locked out of the main quest. So I started over and attempted to interact with her as little as possible and the result was the same--a stalled main quest.
So, my question is this: Is it possible to progress in the main quest without trying to seduce all the females?
