I think that any kind of intimacy added to a game can greatly improve the whole experience itself, if done properly.
If we look at games not just as entertainment but as a nice little escape from reality, then it's normal to expect a deep and good experience instead of some boring and cheap written game. If, like in this case, romance is part of the game, then any intimacy helps building the relationship, it's like in real life, if you love someone, you are likely to have some kind of sexual desire (unless you are asexual, if I get it right) and in getting closer to someone physically, you just give in to the desire and that's fine and healthy.
So there is absolutely no point in 'shaming', unless (and I have to add that) people get really obsessed with it so they spam about it or even raise their IRL standards to match a game, which is something I don't see as healthy anymore, but that's just my opinion (not attacking anyone).
