As of right now, there is no swinging/sharing content from MC's perspective. There will be some in the future. But they will always have alternative content in most cases.So from I gather from reviews and the thread this is mainly a sharing/swinging focused game where that route gets the bulk of the content?
If you play the normal route you will be the only male having sex.
The hardcore mode has a bit of realism.
And no this is not a sharing/swinging-focused game.
