Um, my point was: How can your brain not go 'um, wait, this might not be all that sweet in real life'?
(It's pretty easy to tell apart the ones that are writing their non-con fantasy or whatever from those who just think that handsome/cute/sexy men just can't be rapists and 'but they're, like, soulmates!'.)

...guh, I just remembered the last two seasons of Buffy. I may need a bucket.
