First of all, you have to understand, you can't even hear yourself, let alone your partner. Second, you can always put people on full ignore if you honestly don't want to hear sex in public. I do agree with you that adding another sound setting, allowing people to choose the volume and distance is maybe the best solution. But to say 'no need to fix this', is rather extreme, when it's clearly not working as it's meant to in a game meant for people to have sex.
