That whole scene is stupid. As if the smartest way to feed a starving vampire you met a few days ago is to lie down completely defenseless and bare your neck for him. And then if you change your mind you literally pull a stake out of your ass. And successfully stab a dude while barely being able to stand.

Having a more intimate variation would also be hilarious when you don't stop him from drinking you dry. Imagine having to talk to him in the morning after you let him kill you because you...were distracted.
