TLDR: I feel like piece of my brain rotted with this series.
Dude gets isekaied to be reborn as a goblin....blah blah blah.... gains the power of what he eats..... pulls a Captain Kirk by having sexy with almost everything female. And it's the last part that make my head hurt. This is basically a hentai without the nudity. He literally gets the skill LEBIDO. If the girls are not attracted to him for being OP, they submit to him from Stockholms syndrome and as a last resort, he just rapes them till they fall for him. Whoever came up with this shit watched the category section of a hentai site and asked themself, "How can I squeeze in everything and still be allowed to air on TV". There might as well have been no plot for this to add value to.
To say this show was stupid would be an overwhelming understatement. If there was a show to make you go outside and walk on some grass, this would be it. I genuinely feel bad for the team saddled with the responsibility to make this animation a reality.
All is not lost as the series manages to mediocre enough in other areas as to not be unwatchable...but why would you want to? It's as though there was a demand for a new place on the anime sex scale. [Hentai]->[Ecchi]->[Whatever this is]->[Tasteful Fan service]->[Sex scene that adds value or context to a plot]
