Are you talking about yourself i guess ? :p

incredibly jealous

4,5 year is too much i guess, age difference should be like 1 or 2 year.

It's not the number of years between the people that matters, it's the maturity.

It would matter if it was a 4.5 year old and a 9 year old, in this case...I don't really think it matters :P

4-5 years is a huge difference from my point of view. If he was one of my friends, I'd think about him that he is immature and he cannot get in love with a girl his age.

Just do not get sex with the girl for 2 or 3 years and you are good to go

It's bad not because the age difference is too big, but because she would be like 15 and you know what they say....better be safe than sorry...

Edit: After she'll be 18 you're good to go...4 or 5 years is definitely appropriate...

That's... almost a child.

DUDE

Are you asking this question because you're the boy?

If the boy thinks that the girl is mature enough to handle a relationship long-term and they are happy together, then sure, go for it.
BUT. If the girl is immature and one of them insists on sex, then it could end badly for the boy if they have a falling out, even if she is of legal age according to the local law.
I'd recommend for the guy to think it through.

Depends on, what kind of person this 20yo guy and/or his girlfriend is.
If I don't know this person, I can't really judge on him.
A fitting answer for such a vague question, I think. x)

I've been there (not exactly but similar situation) and must say it depends 80% on the girl 10% on the parents and 10% where you live.

The Bro Code states it clear:

Your Age / 2 + 7

Let's say... I'm 32 so my dating limit is 23 years old girls.

This happpened to me in my youth, i was 20 and she was 3.5 years younger, not really an issue, just try to avoid public displays of love, cause if you get caught, even if it wasn't against her will, she's still underage and it's not gonna end nice for you.

At that age, I say it is bad. If we would be talking about 25 year old man and a 20 year old woman, then it would be fine. But a girl with age of 16 is still just a kid.

I would think of the guy being pathetic and trying to get a thing going on with a naive little girl. It would be more using her, rather than a serious relationship.

the age difference does not matter but the fact that she might be only 16-17 would be a problem to some people. It's certainly not a concern of mine but PDA or even sexual intercourse might get you in a lot a trouble depending on where you are living right now and the legal system there.

Nice try, NSA.

There's an even larger age difference between me and my boyfriend and that doesn't bother anyone I know, the problem is more with how young she is. At least in the country I live in. If you were both in your 20's then 4 years wouldn't even be looked at as odd. But since she's just a young teen the whole thing is literally seen as a form of rape.

There's a big difference between a 4 year old and a 9 year old, and there's a big difference between a 14 year old and a 19 year old. Not so much a 24 and a 29 year old though. Those early years involve a lot of rapid maturation and can be a little crazy. ::shrugs:: good luck to your hypothetical friend.

Oh my god, what are u talking about is a 16 years old girl!!!! i dont really care how u want to write it down to not seems awkward, but hey, this is illegal for a reason! She is a child yet, and no matter if she think that she want it, u gotta be the smart one, who need to know what is right, and what isnt. all i say is that u have no right to take advantage of her stupidity

It's legal but I think that dating someone who is 18 would be more appropriate.

Honestly? My opinion of them would begin relatively low.

There's an enormous discrepency between maturity levels of the average person at 15-16 and 19-20. This hypothetical couple would be composed of two people at very different stages in their lives. One is finally stepping into their own light (out of the shadow of their parents) and the other is trying to find their place in an adult world. A 4-5 year age difference doesn't seem like much, but for a 16-year old someone who is 4 years old has 25% more life experience. The difference is significant, except in the extremely rare instances of an extremely mature 16-year-old.

Additionally, in most states in the US (I am uncertain about internationally) it is illegal for someone who is 15-16 to be in a relationship (at least, a sexual relationship) with someone who is over 18. Other states have very specific exceptions.

Finally, if the 16-year-old girl does what so many women do these days and either sends self-taken nudes to her boyfriend or allows him to take such photos, they are both likely running afoul of child pornography laws.

Thus, in almost every case, I would urge against any such relationship. So what I would think of the older person in that relationship is that they're taking some serious risks, and that the relationship is unlikely to be equal.

i would wait 2.5 years.

Why don't you have a seat over here?

who cares? . . . oh right
