The calls to the crisis lines have a familiar beginning: “I’m not sure this is rape, but …” That's according to a new report, in which victims go on to describe the disturbing practice of "stealthing" — when their sexual partners remove condoms without their knowledge or consent. “I think that when you don’t have the vocabulary you struggle with — is it even real?” Brian Pinero, vice president of victim services for Rape, Abuse and Incest National Network (RAINN), told NBC News.
