Early stories centered around rape themes.
Prices for early games, eventually led to further development of eroge, including interactive games, in the late 1980's and early 1990's.
Most Eroge still markets itself as being erotic, or sexually explicit, however the romance component has been more developed, and incorporated into many modern Eroge.
There are several types of Eroge.
Most of Eroge is SIMS or visual novels, there are many other forms, that include the erotic component, or romance component found in Hentai.
More modern versions, incorporate the romantic aspect, as a prelude to being able to advance to the more sexual eroticism, of the story, or simulation.
