I'll explain why. Christian virtues. As the U.S. and Europe had a lot of Christian influence put to them, many principles became accepted, and still exist strongly today, even in non-christian organizations. These principles dictate that both murder (and other forms of violence) and adultery are wrong. And as such, these principles have impacted the gaming industry as well (along with many others).
Now, it is these principles that create the radically different attitudes towards sex and violence. As stated above, adultery is forbidden by Christian virtue; but it does not forbid sex. Also the other virtue does not totally forbid violence, just unwarrented violence (such as murder, which is unjustifiable killing). Expounding upon adultery (adultery being sexuality outside of a marriage, Christianity also forbids lust, castigating it as a form of adultery. Therefore, as these virtues are still present in the game industry, ANY sexual display inherently brings with it the possibility of lusting to the player (which, of course, is forbidden), whereas any display of violence does not warrent itself to being justifiable. For example, my parents have much less of a problem with me playing a WWII game then they would for a GTA game.
You might ask why, then, is unwarranted violence allowed today? I think the distincition between warranted and unwarrented violence can easily blurred, what with plot and character and all. So the industry has crept a lot faster towards accepting unwarrented voilence displays over sexual ones.
So that's the main reason (IMHO) why sexuality is far less allowed.

To lavish praise upon this title, the assumption of a common plateau between player and game must be made. I won't open my unworthy mouth.
