Setting: Present Day America, in a mansion that houses multiple couples. Vampires, shifters, witches, and humans are co-habitants. Females who can menstruate have been bespelled to do so at the same time every month. All characters are over 21; the couples are strict monogamists.
1 - Would the male vampires and the male shifters be able to smell when the females are on their periods?
2 - If so, would that a turn-on to the males? Is it likely that the male vamps/shifters will want to drink or taste the menstrual blood of their lovers in the form of oral appreciation?
I tried Googling "vampires menstrual blood" but I got poor results. I'm looking for some justification, either supernatural or biological, as to these questions (and their subsequent situations) being plausible or implausible.
Thanks in advance.
ETA: ...Wow. Wow, thank you again to everyone who commented. I really did not expect such a high turn-out for this question because it's so esoteric, but it's all been incredibly helpful.
