personally i dont think that an 18 year old is mature enough to date anyone in their twenties... I dont see anything wrong with an age gap.. but if your 23 and your dating an 18 year old .. she is still a teenager.. totally pathetic in my book..

my rule of thumb is simple.. teenagers should date teenagers..

and if your in your twenties and one of you can get into a club and the other one cant than there is a problem!
