Ken (Thricewise)

Dawn dated Kenny for two months, more or less, although Buffy, Leah and Giles (who only met him on the phone) warned her that he was a "Thricewise." He apparently disappeared after Dawn grew to giant size, which Buffy believes to be a side-effect of losing her virginity. Dawn, later, told Xander that she had really lost her virginity with Nick, Kenny's college roommate.
