I dunno...while obviously, I am sure the intent was not to do this, it really struck me as a bit like (spoiler warning) turning homosexuality into shtick.
The bits where everyone walks in on Buffy and the girl seemed like it would work well on, like, Benny Hill or something like that. "Haha!! She's with a WOMAN!!"
That said, I'm certain that was not the intent of Whedon and issue writer Drew Goddard. It just seemed that way in the issue - using Buffy having sex with a woman as a sort of, well, as the title notes - a "shocker." It doesn't compare well to Whedon's own previous work with Tara/Willow.
Otherwise, it was a nice issue. Bringing back Dracula was cute.
