In 2021, "Shimiken," the top-ranked active adult film male star, released a sex education video titled *Shimiken's Treatise on Love and Sex*, which instantly garnered over 17.6 million views on Y●uTube. The video addressed a common issue many men face: losing contact with a woman after having sex with her just once. This release brings that educational content to life in AV form, offering a highly practical and realistic sexual experience. Most cases of failed post-sex communication stem from problems during intercourse itself, with 90% of these issues attributed to typical AV techniques like aggressive thrusting or rough pounding. This video breaks AV conventions by focusing on genuinely pleasurable sex that works in real-life relationships. There is no artificial staging—no squirting, no intense thrusting, and no creampie scenes. The studio, Seikyoiku, aims to "create AVs that can serve as textbooks, spreading accurate sexual knowledge worldwide and enhancing people's sexual experiences." The acts featured include deep kissing, breast sucking, cunnilingus, "Shimi-cunnilingus," nipple licking, blowjob, ball licking, missionary penetration (holding still for 5–10 seconds), G-spot to cervix stimulation, side position, cowgirl, face-to-face seated position, doggystyle, and R●us·Lois (the ultimate rear-entry position). The climax occurs with a condom creampie in missionary position, followed by a detailed technique breakdown covering: kissing tips, breast fondling and licking techniques, how to perform Shimi-cunnilingus (including G-spot and cervix location), insertion and thrusting techniques (via G-spot to cervix in missionary and rear positions), tips for transitioning between positions, how to perform R●us·Lois (the ultimate doggystyle), cowgirl tips, and face-to-face seated position techniques.
