It appears that _all_ vampires deliberately went out of their way to mock the ethics of the humans who supplied their bodies, including their sexual ethics. Due to this, and being immortal, my opinion is that _all_ vampires get up to all kinds of sexual behaviour, including bisexuality.
This makes me curious; would a vampire who had once been a nymphomaniac human mock the human by adopting celibacy?
You've asked a very good question. My own answer is perhaps 'Yes', for a period. The vampire might 'pretend' to be virtuous for a while; it can always do other things once the novelty wears off, being immortal.
We have to remember that the demons who take over human bodies seem (with the exception of Angel) to be evil to us humans, as they regard humanity as the providers of breeding stock at best, but mostly as food. Remember Spike's regarding of humans as 'Happy Meals with legs'? (I can never look at a McDonald's in the same way again!)
