Yeah, I know it's weird and totally unrealistic but I could keep loving a giant bug just as long as they had more or less the same personality. Though it would be difficult to read expressions and communicate. And the house would have to be kept really really hot.
The point is, according to all the weird interspecies sex happening in star trek it's not bestiality unless one is significantly dumber than the other. Besides, wouldn't the texture be exhilerating?
I guess if it was a fly I'd be more careful. I think I heard that fly semen dissolves the female fly's guts, so maybe I'd do a bit of research first..this article
makes me think twice for other reasons...sorry if I've taken this one a bit too far. Hee hee!
