Call or Fold with AA?

[wegs the wegs]

Table has been very loose but rarely play to a large raise preflop, this is why I made it $13 to go preflop. BB has called my preflop raise the last four times that I had raised on the button, with two folds on the flop and one check re-raise all-in which I folded to. No reads on other players.

Thoughts? Set of tens, queens, even twos. AQ, KQ, QT, AT, KJ, and any two hearts are a legit possibility in my mind for these guys. Is folding an option here or is that too tight? Thoughts?
