I was probably 24 years old before I realized dating multiple people was even a thing. I figured you talked to and dated a person until you either decided you weren't having a good time or you married them.
Note that it's not universally true around the world. In the US, yes. If you do this in the UK, it will result in an evening where you end up ordering a taxi and slipping out the back door while two women are pulling each other's hair extensions out outside a pub and trying to beat the opponent with a shoe.
I think it depends on expectations. I can't imagine how anybody raised in the west would expect exclusivity a) after a couple of dates and b) without a conversation.
As a 24 year old, that honestly just sounds stressful. I feel like many 24 year old have a lot going on, personally i don't understand how people would have the time.
