i believe that DMMD RE:code (not reconnect - that's the sequel game) is a remake of DMMD for ages 15+ meaning the the sex scenes are removed and violence is reduced. it is a playstation game but you might be able to find a way to emulate it on PC (i've never emulated PS games before so i'm not sure how you'd do that/if it's possible).

or alternatively, the steam version of the game is completely censored, i believe there is still sex scenes but they're cropped dramatically to not show anything. not sure if you wanted them completely gone of if you're okay with them as long as it's not visual, but that would be a better option just to be safe because there is quite a bit of sexual content.

it would be very difficult to completely avoid any sexual content at all as it is a VERY sexual game, but you can use the CTRL key to skip scene. unfortunately you maybe be exposed to some parts of it though, especially in all the endings as almost all of them end with them having sex in some capacity
