Although I haven't been married yet, I can confidently say that the main reason marriages turn unhappy is likely due to disharmonious sex lives. That's why more and more people nowadays advocate for "test-driving" before dating and then discussing marriage. However, this idea is mostly embraced by younger couples! After all, Eastern culture has always been conservative, especially Asians who are devout in religion and morals, so premarital sex is still frowned upon by the older generation. So, getting to the point, the series "全裸婚活" is produced by "SOD," which translates to "Nude Marriage Meeting" in Chinese. I think although this theme isn't particularly original, it boldly challenges traditions and combines three elements: first, the concept of premarital testing; second, group sex; third, gender equality. The film kicks off straight to the point, having the men and women on both sides strip naked and present their bodies. Then, they select their preferred partners and go through a mutual body evaluation process, like checking breast sizes, penis sizes, and so on, while also recording each other's sensitive spots and G-spots. Next, they move into the action phase; after mutual servicing and foreplay, they engage in sex with their assigned partners until climax and ejaculation. Finally, the attending staff announces whether the pairing is successful.
