[maybe NSFW] Where do some women learn that if they deny sex, they're a tease?

I can’t remember where I read this, I thought that it was on Fluther but I couldn’t find it. Anyway, where do women learn this? I was thinking about myself, and I know that I’ve been pressured to send nude pictures to people (which I didn’t do), but then afterward I felt like I was a tease and I actually apologized for sticking up for myself.

I wasn’t ever taught to feel bad, or shown anything (as far as I know) that would have sort of infiltrated it into my head as far as I can remember, so where did it come from?

Why did I feel like I had to apologize, and why is it that women sometimes feel like they’re cock-teases if they deny sex or sexual activities? Where does that feeling come from?
