I mean they are out there though.. Straight up guides to better sex. You gotta remember, somewhere there is a guy doing NO foreplay, spitting in his hand, rubbing it on her pussy with the worst of techniques, and hammering her while she counts sheep. That guy could use a few books/dvds/magazines/sex articles on how to please a woman.
Now I'm not sure of this, but I think my sexual skill was definitely learned in Maxim and Cosmo magazines. In middle school, my best friend was a girl who used to get all the seventeen and such magazines... which went up to Cosmo in later years. I was busy reading FHM, Maxim, Playboy.....
But I made sure to read EVERY article about sex in all publications. From 100 ways to please your partner, to bad sex stories, to ways to spice up your marriage, to instructional pornos where two stars would "teach" ways and new possibilities... Hell throw Joy of Sex and Kama Sutra up in there too... Real Sex... all that
And when I have a new partner, and they cum fast, or a lot, or just that rare occasion where they don't usually, but now all the sudden they are... I chalk it up to me remembering all those "do this, don't ever do that" type of things.
Example... I definitely remember reading about how to properly eat pussy, years before I did it. So my first time, I was damn near textbook... But she covered my face in her juices in record time. Now of course I know, one size doesn't fit all. You take the good and mix it up with what your partner likes, and mesh the two together.
But if you're really out here struggling to please any woman you come in contact with............ Gym (every part of sex is a workout, including refresh time) and then technique
