The first chapter isn't bad despite the fast pace, and may turn out to be a moderately fun harem manga. That said, yeah, it's a "teisou gyakuten" manga which takes way more inspiration from Infinite Stratos than the actual OG Teisou Gyakuten Sekai. At least, judging from chapter 1. It's a story of a world where all men have low status besides the MC and don't enter women's eyes, and [probably soon] women come onto him constantly.

https://mangadex.org/title/547b5366...9-male-to-female-ratio-is-unexpectedly-normal are more in line with teisou gyakuten. Having the women being horny but trying to hide it to not be disliked by the male lead, undervaluing their own appeal, while most men are timid or high-strung around women is part of the charm of the genre. Women constantly raping men and being sexually aggressive doesn't relate to "sexual modesty" because the modesty has been completely thrown out.
