18 year old dating 26 year old
If she's mature then it shouldn't matter, but in most cases I don't think it would be true.Of course according to the law it's ok, but I would try to stop my daughter (or my son) at any cost from getting into that sort of relationship. I'm now 22 and have been with my 34 year old partner for 3 years in May.
For example kissing, holding hands the works I understand the age of consent in Washington is 16 and...
It's not the most common situation but I can't see anything wrong with that.
When I first met my current bf three years ago I was 18 and he was almost 25 so we had a similar situation.
Mainly because I think 22 year olds are more grounded whereas 18 year olds are still slightly in the process of maturity development (both physical and mental).
Somehow I find a 46 year old with a 22 year old better than a 26 year old with an 18 year old.
