It may (may) be rotten intentional deception, and somewhere maybe that's a crime in and of itself, but it's not rape.
People lie about pertinent shit all the time trying to get in someone's bed, either directly or by implication (or by omission). People hide felonies, bad habits, hygiene habits, ugly or unsavory genitalia (even original equipment), marital status, financial status, communicable diseases*, psychological issues, unsavory personal history that would be deal breakers for you if you knew, you name it.

HIV/AIDS transmission/attempted transmission has been treated differently in some places/cases, sometimes depending on intent or other factors, but it's more akin in the legal system to assault than to rape. https://www.cdc.gov/hiv/policies/law/states/exposure.html
Connecting with any person carries some level of inherent risk. The faster you hook up, the less diligence you do, the more the risk increases. If you choose to have consensual sex based on little to no diligence, caveat emptor. 20 minutes later or the next day you might rue the decision, but it's yours to sort out. Especially if you were deceived. But you have the responsibility to own what you yourself set as the level of vetting, if you engaged in the act consensually.
That's completely different than someone forcing sex on you, whether violently in an alley or non-violently ignoring a no/obvious lack of interest/participation in your shared bed, and the things in between. That act is the crime, and that is the difference between being shady and being a felon, between being treated like shit and being raped.
Rape should not be defined down to meaninglessness. We rarely get justice for actual rape, and throwing in the kitchen sink just makes it harder.
