So i wanted to get the vampire teasing scene so i could progress with jenny but the problem is i already married the vampire before i did the vampire teasing scene so now the vampire keep repeating the same marriage dialogue instead of starting the quest. Is there anyways to fix this problem ?

The teasing scene is required before the marriage events can start. If the scene is flagged as done, but you don't have it yet, then something was broken before you started the marriage quest.
You can replace this map file in the www/date folder, to change the dialog for Vampire in the sleeping chambers, but I don't know if that will fix all issues you have, since the events were not meant to be played in that order.
