Agreed on the humiliation stuff, also not a fan of the gay stuff.
Having said that it does something I wish you saw in more games - like a "reverse ntr harem", as in it's planned out as a broad sandbox with a bunch of different male npcs the girlfriend can meet up with at any time.
Most sharing or ntr games have scenes more as one-offs, like a secondary. It'd be a fascinating idea to have a wide open sandbox with a bunch of different independent missions that resulted in sharing events for the gf/wife - think something like "Love and Sex Second Base", except instead of forming a harem for the player, it's forming a harem for the girlfriend.
