Obtaining sex by deception, or bullying which does not involve physical violence or the threat thereof, for example, is still going to get you charged with rape in most places.
This is not an accurate statement of the law in common-law jurisdictions, nor, I suspect, of the law in most other Western countries. With some narrow exceptions—such as impersonating the victim’s husband, performing sexual acts under a false pretense of medical treatment, or failing to disclose a sexually transmitted disease—enticing people into sex by false pretenses is usually perfectly legal in these jurisdictions. In the past seduction was a common-law tort in its own right (and sometimes even a statutory offense), but seduction by lies was never considered as a form of rape.
As Richard Posner writes in his Sex and Reason (which I can’t really recommend otherwise, but whose statements about law are reliable given the author’s position):
The law usually treats force and fraud symmetrically in the sense of punishing both, though the latter more leniently. It is a crime to take money at gunpoint. It is also a crime, though normally a lesser one, to take it by false pretenses. But generally it is not a crime to use false pretenses to entice a person into a sexual relationship. Seduction, even when honeycombed with lies that would convict the man of fraud if he were merely trying to obtain money, is not rape.
