ELI5: why are there almost no video games with sex even though we have 18+ rating and gore is ok?

All video games released to the public in North America are  required to be reviewed by the ESRB before it is allowed to be distributed and sold. ESRB gives videos games the ratings E, E10+, T, M, or AO (Adults Only). However according to Wikipedia, "all three major video game console manufacturers (Nintendo, Microsoft, and Sony Computer Entertainment) refuse to allow AO-rated games to be published for their platforms." So releasing an AO-rated game in North America would make no money since literally no one will sell them. Thus, that is why there are no AO games in North America. Japan, however, where ESRB does not regulate, is a whole different story.
