Re: How come Teenagers can't flirt? ~The Sims 4~

There is no 'Romantic' button, nor any flirt/compliment appearance in any section. 

They both need to be teenagers and can not be related or there will be no romance interactions available.

This is happening to me too. But also with adults/young adults. It's really weird. I even aged up one of my sims because they were barely a young adult and I was trying to flirt with a young adult that was almost ready to age up. I thought that it thought that the one sim was still a teenager or something, but aging up didn't work. So definitely don't age them up, because it won't help.
