Yup, they need more kissing options. I'm not sure if my memory is wrong, but I remember there being more types of kissing in Sims 2 specifically. I also remember the make out interaction being available on the bed. And I swear the make out option on the couch was more involved in previous games than it is now. There should be enough types to accommodate different personalities. There should be somewhat casual interactions, shy interactions, clumsy interactions, sweet/romantic interactions, and then hot and heavy interactions for sims like Don Lothario. It annoys me that a game rated T for Teen can't even give us content that would be in a PG-13 movie or a CW show that's made for a teen audience. Just sayin'. I realize they've changed their target market and seem to be targeting younger kids now, but it makes the game so childish and not in a quirky, fun way.
Most people will say there is a mod for that, and I do use the passionate romance mod, but I won't use that other one that is way, way too adult. I would like the Sims 4 dev team to fix the romance system, please.
