As someone who usually finds sex scenes in games like this very awkward, my solution would be to ask for less awkward sex scenes instead of complaining that a game meant for adults portrays characters bumping uglies. Optional portrayals at that, since we can skip or entirely avoid them.
By all means, I'm for making it less awkward, but the idea that it somehow "ruined" Baldur's Gate is silly. If an optional scene ruined the whole thing for you, you probably have a less than healthy attitide towards sex and sexualization, and you should be looking inwards to solve that.
Don't you just hate it when people with dumb opinions have nice avatars?
