I have trouble believing that claim.
I did too, when I first started putting it to the test. And most of the women I talked to were pretty shocked even as they listened to themselves talk.
I was curious about this a few years ago, so I started asking any woman I knew who I felt was comfortable enough with me to answer. I phrased it as something along the lines of, have you ever had sex they didn't want or were unhappy about, in order to make it easier to get away, or to keep him calm, etc. Something along those lines. And from there, I shut my mouth, and they talked.
I expected a large minority to say yes. But that's not what happened.
All said yes without exception or even hesitation. Most told me their stories. As in MULTIPLE stories. Nearly all of these women, with the exception of a lesbian who had sex with men fewer than 5 times in her life, had been through this MULTIPLE times. In some cases, too many times to count. For an unfortunate few, this was their entire sexual relationship with their partner.
And it wasn't until they sat down and started talking about it that they realized what it was. To women, this is just how the world is. The world cares so little about our consent that settling for a lesser assault is preferable to risking a bigger one; not being assaulted doesn't even seem like an option, and for many women, it probably isn't.
Believe me, at the time, I was shocked too. I didn't expect this either. I thought we'd come further than this. It was a cold slap in the face to realize we haven't.
