Hard agree on the voices, and similarly music with vocals. There's been maybe one or two games I can think of where it worked, but it completely kills the mood for me most of the time. Goofy sex music man. I've had my ears blown out a couple times by main menu music too but thankfully it seems like that trend has calmed down a bit (or I'm getting lucky).
I have become more of an advocate for good sound/music choice in lewd games as it personally does a lot for my immersion, but when you hear the same selection of royalty free stuff over and over you start to tune it out more than anything. Think that's why I really appreciate when a game puts a little more thought into the soundtrack.
