You can't blame him.......Who doesn't like bacon? honestly! If you don't eat bacon your not a man! (that first female orc was horrifying) John Goodman huh? Urak Ki also? The author don't give a shit. lol
Even better - his girlfriend misinterpreted a sign at an evil shrine by accident at the beginning before all this and prayed/ gave offering which made him sterile.
Honestly though with magic of elves or something I could see any sterile problems go away, this is a magic world after all. But key thing here is id any actually got pregnant they would brag and the news would wreck the story cuz it'd be widespread that the strongest dude is a cheater.
The discrepancy of beauty is pretty funny for orcs, I’d figure the ugly ones would just move to human kingdoms where they’re considered beautiful right?
