Funny story, when I was a teen in high school our sex ed teacher ran a test on all the boys. She asked us "have you ever raped a woman before." Everyone said hell no. She asked "have you ever pressured a woman to have sex with you after she said no."
It got quiet. One guy admitted he did but she was cool with it. Teacher made it very clear that that is also rape. No means no, and any further action whatsoever to get her to have sex, even if she ultimately agrees, is rape.
Everyone was floored and silent. Some argued with her a bit. But that was the day I realized why sex ed is important and needs to be in school. I know I took the lesson, and I think a lot of fellas changed that day. If I ever ask a girl I been seeing for sex and she says no, that's the end of the story.
