I know this is a bit late, but I went through all the replies and I think people missed an important bit. Condoms protect against more than just pregnancy. As a sex worker, she's probably on her own birth control and the condom was a barrier against diseases from an unknown partner. That's what really pushes this into the rape category.

While your example of a woman lying about birth control is close, I don't think it's a 100% match like you think. I.e. if he really didn't want kids than he probably should have used a condom or gotten a vasectomy instead of trusting it on another person.

This I believe is about having unprotected sex with strangers. She didn't consent to be exposed to his bodily fluids at all. And part of the agreement was he would not expose her to it. He said he would wear protection then took it off and possibly exposed her life threatening diseases. How everyone missed that is beyond me.
