Homosexual relationships are also possible, as there are games with no specific gender lines ("all pairings").
There are also Girls' Love games, which focus on female/female relationships, and Boys' Love games, which focus on male/male pairings.
Sexually explicit dating sims may fall into the category of H Game or Eroge.
Eroge only gets released to PC because large Japanese game companies do not want to release games with sexual content on their game consoles.
Some Japanese dating sims may allow the player to have romantic or sexual relationships with characters in their teens.
