One other thing occurs to me. My mother, I guess because she enjoyed making me squirm, would sometimes let slip details about her sex life. One anecdote, however, was instructive.
Apparently when she and my father were dating, they were approached one day in public about her taking part in a sex study. When they got home, she went off to go fill out the questionnaire they gave her, but my father stopped her and suggested they fill it out together, which they did. After that, she said, the sex was outstanding.
Maybe this isn't totally relevant to the OP's situation, but perhaps she could contrive to do something similar, and anyway it does speak to what's possible if people take (and are given) the chance to learn how their partners' bodies work.
Ms. Shere Hite found that about 6% of women masturbate face down using their hands. Shere Hite, The Hite Report 76 (Dell 1981); Shere Hite, The Hite Report 88 (Seven Stories 2005). Check it out—it's a wonderful read!
The Hite Report should be mandatory reading for high schoolers. Failing that, PornHub I guess.

The Hite Report (scanned copy; Amazon) might answer some of your questions.
Do you have any decent books on sexuality on your family bookshelf? A major motivation for my young porn-viewing habits was curiosity (and fascination); if I’d had <em>The Hite Report</em> and <em>Our Bodies, Ourselves</em> and maybe some fiction with some good, sensual, not gross sex scenes (Middlesex comes to mind) around to borrow—I read all the “good parts” in our encyclopedia and family doctor-ish books—I probably wouldn’t have watched porn until I was well into high school, if then.

I can't find an actual link to the study, here's a link to the book she wrote after the study https://www.amazon.com/Hite-Report-National-Female-Sexuality/dp/1583225692
But this is interesting, this is on the wikipedia page about her Methodology Hite used an individualistic research method. Thousands of responses from anonymous questionnaires were used as a framework to develop a discourse on human responses to gender and sexuality. [b]Her conclusions were met with methodological criticism[/b]

As is common with surveys concerning sensitive subjects such as sexual behavior, the proportion of nonresponse is typically large. Thus the conclusions derived from the data may not represent the views of the population under study because of sampling bias due to nonresponse
So ya, her data was probably crap that she based some of her findings on ..
My bad though, cited a few google results with just a skim read
