Kamog, I personally don't think if you are and "adult", you should be dating minors. But hey, that's just my opinion. For what it's worth!
As to what the acceptable age difference is. It is what you can stand. It is after all, you and the other party involved. It really makes no difference what everyone else thinks. So, what you can stand, in terms of "stairs", "rude comments" and sometimes just being "ostracized". What your physique can stand.
