Reddit reviews The Sex Myth: The Gap Between Our Fantasies and Reality

I definitely think that's part of it. To give an example from some Christian feminist bloggers I read, they had some sadly distorted views on sexuality thanks to both the oppressive purity culture and the hypersexualized secular culture.

Their boyfriends manipulated them into sex since "that's what you do in a relationship," and later used the first-time sex "no one will marry you now since you're not a virgin" to keep them in abusive relationship.

Take the lack of good sex education, add in both the easy access to porn and the availability of porn with taboos, and mix together with toxic masculinity. What we might get is more young men expecting (and thus pressuring) certain sex acts from their partners. If you spend as much time as I do lurking in /r/relationships, you'll see these problems already exist.

Also, I found the book. This is an Amazon link, but not an affiliate one. It's called The Sex Myth: The Gap Between Our Fantasies and Reality.

Also, these are not the particular essays that I had read, but they're still enlightening.

I use that word broadly, since obviously not everyone will agree on what is or is not a taboo. Blow jobs used to be taboo, and now they're not, for example.
