I'm 27 and the longest relationship I've had was about 2 weeks when I was 18.... : P
Though I think that's just me being generally undateable and scared of people.
I hate this whole thing where society at the same time is like TEENAGERS SHOULDN'T BE TAUGHT ANYTHING SEX RELATED!!! but then all of YA novels and media targetted towards teens is full of nothing but...just that. I remember when I was 15 and had just started high school and I was talking about something where I alluded to me being a virgin and two of the girls laughed at me and were shocked I hadn't done it yet. Like....I WAS FIFTEEN???
But yeah this whole pressure to be dtf and getting married and having children in your 20's is ridiculous. I've long been wondering why my generation seems so superficial, I remember being on a date with a guy and he kept apologizing for his acne and I was like bruh I wouldn't have even noticed if you hadn't said, I could not give less of a shit about your skin and he started crying (and he was this jacked gymbro). I feel like that speaks volumes what kind of expectations people have when it comes to dating. It's dumb and I hate it.
