I’m afraid I don’t agree. I think women need to get over not wanting to say no.
My daughter was raped when she was in her 20s. Years later she realized that she allowed it to happen and took some responsibility for her own safety. That doesn’t excuse her rapist, but she willingly put herself in an unsafe situation. And she froze rather than screaming, which would have awakened someone sleeping in the home. She learned a horrible lesson, but it has not happened to her since.
As for having sex with someone because you feel embarrassed to say no and would prefer that someone simply guess what you are feeling, that strikes me as ridiculous.
Say how you are feeling, ladies! (From an old lady who was brought up in a different time.)
