A bicorn creates a harem of 5-6 "easily" so I'd expect even the average bicorn harem to be larger than that.

More Importantly the Bicorn profile suggests that the reason men don't get harems as eaily is that demon energy from his wive(s) is absorbed into his body and marks him as "taken" which while not innately preventing a monster girl from going after him makes him less attractive to monster girls not already in love with him. The bicorn demonic energy counteracts this effect meaning even a man with several wives will still appear highly attractive, and the limit to the size of the harem is based on the strength of the bicorn's demonic energy in comparison to the harem. This means it should be possible to increase the size of the harem infinitely so long as at about 20% of the harem is made up of bicorns. Eventually some of the wives would get tired of having to share with an ever increasing number of individuals and try and put a stop to it though. Thus actually having a truely infinite harem would probably require a harem consisting solely of bicorns since they derive a greter amount of pleasure the higher the number of sexual partners their husband has had, and thus wouldn't complain no matter how large the harem became. Bicorn are probably relatively rare monsters so an individual doing this would probably just get a hnadful of "wild" bicorn then add his own descendents to his harem to keep it going, which in theory would allow one to achieve immortality according to the method mentioned above.

Also if the goal is immortality it would be much easier to just go to Pandemonium (home of corrupted divinites) since time doesn't pass there making you immortal as long as you don't leave.

Lastly for the communal husband type monsters I assume the monster girls are "related" and thus the pressence of one's demonic energy in the man isn't a turn of but a turn on due to it being similar to their own, thus the size of such a harem would have more to do with the size of the "family" rather than a specific number. In other words two unrelated dourmice probably would not want to share a husband while if a dourmouse monsterized a town that only had women in it they would probably be fine sharing a husband even if there were an extremely large number of them.
