well, I hear that social emo's(the ones who are frantic cutters) is a good place to start.

but you are right. I mean. you really can't do that unless you are asking for publicity, but that can get you in awkward situations such as:
strangers walking up to you and asking if you drink blood
the non-believers start crap with you
people excommunicate with you
you might be hunted, since I hear thinks in Spokane, Wa that they have "werewolves", or you can get hunted by a human or conformed religious guy "most likely not"

Hopefully you will find somebody who likes blood, or likes vampires, or likes you. To be able to donate, on the Biting -vs- cutting situation. if your donor or vampire whom ever you getting blood from likes pain, and heals quick enough. I guess you can bite. also it is much funner, but you can also bite on a cut that makes it bleed more.
