But would the vast majority of men have sex with those women WITHOUT plastic surgery, makeup and push up bras? If not, then you are actually arguing that those women rape the men by having sex with them?!
No I'm not.
Seriously, this argument is getting pathetic. First, because plastic surgery is not "lying" about her look anymore than medical surgery is "lying" about not being sick. You go in with appendicitis, get surgery, then you can say "I don't have appendicitis", and it's not a lie. You really don't have it anymore. Similarly with plastic surgery. It's not "lying about your look", it's changing your look. You looked one way, then you went in for surgery and came out with your default look being something else instead.
Now you're free to be bothered by it, and even refuse to have sex over it, but that goes into the "Tell her" stage of thing. If, AFTER you tell her, she lies to you about it (or does not admit to lying previously, or otherwise leave you to believe she never had surgery)? Then yes, she is lying to you in such a way that it is rape. But that's only ONCE YOU TELL HER.
Second, "Improving your look" - and that covers the whole gamut from wearing your most fashionable and stylishly combing your hair to make-up and push-up bras is not a lie (it's presenting yourself at your best, because the person under the combing, shirt, etc is still you, and this is still something you have the ability to look like when you chose to do so, even if it's not what you CHOSE to look like in normal circumstances.
Third, EVEN assuming it's a lie, remember the "It must be a lie a reasonable person would believe?" If you honestly believe that someone who's playing the seduction game on you isn't using all the means available to them in order to look their best, then you're the one not being reasonable.
VRWC - Yeah, well, given we're dealing with human nature here, and not perfect not-until-marriage-and-lets-wait-a-while-before-we-get-married people who have always been a quite rare sight, I think we'll make the laws to protect everyone against a-holes, not just those few rare gems.
