Before I touched on this point I wanted to check in game myself to get an accurate count.
I'd agree this isn't a brainless game, there seems to be a lot of thought put into the characters, their motivations, personalities and the overall plot.
But even though we seem to be still in the early stages of this game the MC has had sexual encounters with a lot of women. 11 already so far to be precise. Some even when first meeting them including Moonsong, Emerald, Isabella, Meredith and Sapphire . Others after knowing them a bit Amber, Anna, Arwen, Evelyn, Cat and Lucia .
That's getting action at a rate equal to most fuckfest games I've played, easily.
Which ties into my previous point about it being unlikely the MCs powers will become a problem as far as him having sex. This is a fuckfest, just one with a purpose. And that'd be completely disrupted if suddenly the MC can't fuck anyone but Ruth without risking hurting them. Especially in a harem game.
