whoa. a lot of arguments going on here! these are just personal opinions, so whether you agree with them or not you should still respect them, we aren't making official laws on dating here!
Age does NOT define maturity, intelligence, physical development or anything else. It is an idicator of the developmental stages most people go through at that time in life. For example, most people hit puberty around the ages of 13 to 18, but it could be younger or older for another individual. (just using "puberty" as one of the stages a person goes through in their life.)
So, what I'm saying is that people develop and learn at different rates; a 10 year old girl may act, think, and look like her 15 year old sister. Or the other way around.
A 25 year old man could use and hurt a 15 year old girl as much as a 15 year old boy could. It depends on their personality and how they feel about the girl that makes them act the way they do, not necessarily their age.
I'm not saying that all teenagers/minors should go out and date all the 20 and 30 year olds, because they are often at different stages. The younger people are still in school and should be making the best of their childhood and not rushing off to the "adult world" and the older people probably have careers and want different things like a family and marriage.
BUT, if a young person and an older person really have true feelings for each other and love to be together, and they will wait until an acceptable time that they are both ready for marriage or intimacy or a family, then they should have the freedom to be with each other.
The thing is, many people are emotionally immature. If 2 people are emotionally mature I think their relationship can work no matter their age. For example, my brother is in his 20s and he is not emotionally mature. When he had a girlfriend he told her that he loved her (which pissed me off cause he has NO clue what love is and he was clearly infatuated) and he always called her his girlfriend, instead of her name (she is not a possession she has a name), he was convinced he was going to marry her (slow down, this is your first girlfriend), and when she broke up with him he cried his heart out.
I never told my boyfriends I loved them and wasn't upset when they broke up with me. I know there will be more in the future and that the best time for me to get into a serious relationship is after im finished university or find a career. I know the difference between love, like, and infatuation. and I don't let guys use me.
It is not IMPOSSIBLE for a relationship to work out perfectly fine for someone very young and someone a lot older. However, in most cases it's best for people to date others around their age, give or take a few years.
