I take your point about the mind projection fallacy, but actually in the particulars I may have to _slightly_ disagree.

Consider these themes:

Furries Anime tentacle rape Bestiality/zoophilia etc etc etc...

In other words, we already know that there can be humans that find stuff either slightly human but modified, or increasingly alien to also, ahem. "tweak" them.

I bet somewhere either the author of that story (with the plant) that you mentioned, or some reader somewhere found that story _particularly_ enjoyable, or at least the notion of it.

So, it does seem reasonable to suppose that _some_ alien species would contain _some_ mambers that have sufficiently different or broad or... creative... sexuality that they'd even find the scandalous notion of being attracted to a human, well, attractive.

Clearly then the Bug Eyed Monsters coming after the ladies in torn dresses are simply the deviants of that species. They're self selected! (okay, was being somewhat silly throughout this entire comment, such happens when I am on lack of sleep...)

Benquo: Wait... what about Chupucabra? Clearly simply a very confused alien that's simply trying to find a mate! *chuckles*
