I dont mind being punished for playing the manwhore path IF the punishment (that usually is a bad ending) is indeed warranted.
For example, until the MC officially enters a serious relationship with any one of the LIs, being a manwhore shouldnt, in my opinion, be punished.
Now. if the MC continues to be a manwhore after accepting a serious relationship with any of the LIs (essentially cheating on them), I will gladly take responsibility for my selfish actions and face whatever Hell of suffering/pain DPC has in store for my MC
