Is good to build some story/tension between the characters but if it takes too long to have a sex scene the game coulb become a crap, like a Wife and a Mother.
another thing i hate is when the use sex scenes in dreams... that kills the atmosphere
but you are saying it like you are the representative of all players. Using words like "nobody wants this or that". Is just your opinion and there are a lot differents out there. Im sure some people likes exactly the opposite of what you said.
If i see a game that caught my attention, the rating doesnt matter at all. But searching for games i would try the ones with high rating that doesnt match my preferences
