I dated a girl that was 13 when I was 16. She told me she was 14 and almost 15, and I believed her because she...erm...had already filled out nicely?
Anyways, Tosty, I'm not attacking just you, but everyone at this site that does it too. When you are a teen you date to have fun. There are no major relationship decisions until you guys start doing shit like fooling around. If the youngin (Young . Gin) is mature enough there is nothing wrong with it. At first I wasn't even going to date her because I didn't know if she had the maturity, but she proved me wrong. After dating her, a girl who was a year older, and a girl that was two years older, she really was mature when it came to being in a relationship.
It depends on the person, not the year on the birth certificate. Some 20 year olds aren't even mature enough to "make mature relationship decisions."
