Having sex and/or nudity in video games has been around for... as long as video games have been, and it's always been controversial. Sex sells, period.

Back then having even moderately discernible shapes in your pixels that just might look naked was exciting (this was the era of scrambled porn after all). So naturally, game creators took notice.
