Ayreos, as a young adult myself i kinda have the same feelings as yourself, just one guy with lots of girls, the guy is always a herbivore, OP and getting dragged around. Its like a plague, but understable when you think this is aimed at guys at their teens with raging hormones.
I personally find more enjoyable when there is just one love interest who answers maturely and some trustworthy male companion (or a gender balanced party) to have ocassional bro-mance, would it kill the authors to add a nice wingman? Same sex will always have a deeper trust in certain aspects, i would be permanently on edge with an all female party around me, that fantasy looks like hell to me. Up to date Grimgar has been the closer thing i have found for mature public (one time the dudes just decide to hit the brothels), much tragedy but not your average isekai.
