Oldest a 17 year old can date

It's hard to say because everyone has different opinions. I'm 19 and would feel a little strange even dating a 17 year old because we are at totally different points in our life. The oldest socially acceptable age is probably like 20? I think that's a bit too much of a gap personally though. As long as everyone is happy and there's no power imbalance do what you want

16-18 is always a bit of a grey area. The way I think about it is, 17 is a child. Although if you were a few years older it wouldn’t be so much an issue, as a 19 year old I would not date someone under 18. Would it be somewhat okay to date a 17yo? Most likely. I would not be comfortable in it myself.
I think of it as they are literally in year 12 whilst I have had a gap year and going to uni next year; we are at very different stages of life.

I’ve met people who are 21 and 17 and to be that was on the line!
A friend of mine is 18 almost 19 and with a 24yo, if I didn’t know him personally (and know he’s absolutely perfect for her)I would not think it was great. But they also met at work and I feel like age is a bit more irrelevant when you all work together.
But if you are older than 19 I would say until they turn 18 atleast it’s seen as less socially acceptable.

I'm 22 soon to be 23 so slightly younger than your friends girlfriend, I think It should matter too much as long as everyone is happy. I was just trying to figure out if some people might be against it simply because of what society is accepting towards

How old are you ? You are both over 16 and you aren’t in a position of trust so I guess you shouldn’t be bothered about other people’s opinions ??

Normally the guy is older in these relationships is another factor. I’m 18 and wouldn’t date anyone under 17, but that’s me.

9+10=21

.?

21 is the max. It was a reference to a vine video.

What's considered a power imbalance if both people in the relationship are happy I think it should be fine, I just wanted everyone's opinion on at what point it might not be.
