Bidet of Evil
Not really out of character cause Joss Whedon originally wanted to make Xander gay, but decided on Willow which is why they say in the beginning of the show they had gay references associated with Xander like the whole storyline with Larry in Season Two, and then also the little reference they made in Season 7 "First Date," where Xander was like that's it I'm going gay, Willow make me gay, gay me up or something like that.
I think it would be out of character for Xander to have an affair with Dracula not just because he's a vampire or just because he's a guy, but because he's a vampire and a guy and also because it would come so close on the heels of Buffy's experimentation. See what I'm saying? I know there's some subtext there with Xander. I just don't want it to stop being subtext and become text in this specific scenario. The timing, the fact that Drac is a vamp, and the fact that he's a guy make it seem too fan-ficky for me.
