Yes, as severely as rape
Yes, but less severely than rape


Sexual coercion is rape. Period. What else could rape mean? We could also have a category called, say, aggravated rape, or apply additional charges for rape plus assault, if there's a need to distinguish between levels of violence.

This would, of course, require that the legal system starts to recognize that consent under duress isn't real in sexual circumstances, as it already acknowledges duress in contract law. I don't know enough about the law to know how difficult this change would be.
