[basks in praise] 
Seriously, though: some of the partners described on this thread are just out-and-out abusers, and it's unlikely that a significant cultural change from "well she didn't say 'no' out loud at the moment of penetration therefore I am not a rapist" to "if I'm not hearing 'yes! more!' every step of the way, why would I even want to have sex with that person?" would change an out-and-out abuser's mindset. BUT some men, perhaps manipulative, needy, unpleasant-but-not-actually dyed-in-the-wool rotters, need to learn the extent to which our rape culture is excusing them coercing their partners into sex. Men are as saturated in rape culture as we are: culture that tells them 'women are the sex class' and 'women exist for men' - christ, every advert showing a skimpily dressed woman draped over an item on sale gives us these messages!
We fought so many battles to establish "no means no" but what it has left us with is the responsibility to say no loudly, clearly, repeatedly - and be called a bitch, moody, asked why we don't love them any more, be blamed for making them feel unattractive, asked where is our commitment to this relationship, be cold-shouldered, sulked at, nagged, passive-aggressively threatened that the relationship is in trouble - from men whose response to a discussion about the ethics of coerced sex is always "she didn't say no, so I am not a rapist. I'd never keep going if a woman said no. I'm not a bad man."
this article is about something slightly different but addresses that idea that men 'don't intend' to coerce when research indicates that actually, they know exactly what they're doing.
I'm sure you guys could generate all the excuses on your own: Claiming that men don't really know what's appropriate and what's not because women make it so complicated. (This has been demonstrated untrue with research, though common sense should also apply.) Denying the difference between flirting and cornering women in hopes that the implication of fear will grease the wheels for you getting your dick wet. Claiming that introducing a whiff of coercion and fear into a situation is okay as long as you're willing to take no for an answer at the end of the day. In sum, men who corner women know what they're doing. And yes, they are relying on the fear of rape to grease the wheels towards getting laid. Rebecca may not have put it that way, but being a mean ol' feminist bitch, I'm happy to say it.
Getting away from "I understand that 'no means no' and so I am a good guy! That time I whined until my partner let me do sex on her even though she wasn't in the mood - that was totally okay because she never said no!" is vital for our sexual health and relational happiness. It's not my responsibility to say "no" all the time, or risk being pressured into sex I don't want. It's my partner's job to seek a "yes God yes!!", and not think any other kind of sex than sex with a willing partner is acceptable. *
But we have to start teaching that right now, in schools, homes, to everyone we talk to. And it's depressingly hard for some people to get their heads around. "She didn't stop me" isn't enough.
*And that's true in a reversed situation, incidentally - I think the onus is always on the person initiating sex to get that enthusiastic 'yes!' - regardless of gender.
