Rape is not the same as "sexual intercourse by deception." The key variable is consent.
"Sexual intercourse by deception" could cover anything between having sex while lying about your age (definitely should not be illegal) to having sex while lying about your seroconversion status (often is and probably should be illegal). None of those count as rape, though, because consent had been granted before and during the actual act.
Lying about your long term intentions in order to have sex with someone, or using sex to manipulate someone? That makes you a bad person, but it's not illegal, and you have a really long line of people to arrest if you think it should be.
