You can not have romantic interactions with your own children or any other children or teenagers when you are adult. You can only use flirty introduction when you are in a flirty mood and the aforementioned is not true.
Also I try create new sims in other house. Flirty introduction still not exist for any sims
@sunsabea, and @jpkarlsen , the Flirty Introduction is unlocked at Charisma Level 5! So that might be why you can't find it, @sunsabea . 😉 There is an even more powerful type of flirty introduction called the Enchanting Introduction that unlocks at Charisma Level 8! 🥳
@sunsabea, I just thought of something that might help. I was wondering if you were referring to the fact that sometimes certain interactions have a color edge that is on the interaction --it happens when they are in a certain mood. If they are happy, then interactions like "Brighten Day" will have a green edge. For Romantic interactions, your Sim would have to be in a Flirty mood to get the flirty actions to have a pink edge in the interactions menu when you click on another Sim, It is rather difficult to describe in the first place, and I was thinking perhaps since we both have different languages that are the languages we normally speak, that there could be some misunderstanding due to that as well. 😳🙂 An easy way to get a Sim in a flirty mood is to watch the Romance channel on the TV. There are other ways as well, but this on is easy since most houses have at least one TV! 😉
