So you want to know how strong you should be? I think that no matter your age, height, weight, experience... everyone will be different there are no standards to compare to and better yet no real reason to unless you want to compete. Generally I believe that as long as you are healthy and you're stronger than you were the last time you lifted (to an extent) that in itself is strong enough.
However, I did find this site when I was looking for strength standards which I can't really attest for: Strength Standards.
I guess according to this site you shouldbeshould be able to bench around 125lbs? (1RM)
