Yes, in a word, as people are becoming more liberal in games, after we saw from the famous sex scene in "Assassin's Creed II and Brotherhood", which showed this a lot more, and there are definitely, even in lower rated games, sex references and jokes, which to the age group it is aimed at, irrelevant, but to the older population, this could be seen as shocking and offensive.
To finish, video games will only continue to contain more sex references and scenes, and so, video games are definitely getter "sexier".
