Help me find the name of an old Vampire flick

...I am looking for the title of a 60s/70s vampire film that i remembered from when I was young. I remember hardly anything about the plot or what actually happens in the film (or the cast). All I can remember is in one of the last scenes a good looking vampire women walks some guy down into a basement of some sort with candles burning everywhere....She tells the man "this is what I am" (something along the lines of that) bites him on the neck and that was all I remember.

I know that this is not much to go on, but if it rings a bell with anyone please give me the answer. Ive been looking for a few days at possible films that could be it- but so far no luck. Thanks!
