How is it that Neelix knows so little about the species he is in love with as to not know about the elogium? Wouldn't you, if you were in a committed relationship with an alien species, want to know about their reproduction? Now maybe it is like periods in that the women don't sit around chatting with the men about it and maybe he just never wanted to ask.. but I think it does show that they were not sleeping together at this point in the series. Otherwise they would have had some conversation about reproduction at some point and Neelix wouldn't have been all ".... wha?!" about the whole deal.
