Are you plan to put any romance in this game? Right now it's just a fuckfest and the only relationship with girls is FWB
He's walking dildo for most of them, so fuck buddies relations in this scenario is quite normal, don't forget about sharing, it's not possible to making any good romance when that stuff is involved.
Many girls also don't care about him and lusting after each other, even if lesbian is disabled.
Game reminds me of all these AI/NTS avns with cuck husband/bf who love to watch his wife fucking the whole city :)
