AdJd in BB

[JustOnce]

I play mostly ring games and do well in SNG's, tonight was my first shot at NL, played the 25NL tables, and could use advice on several hands I played but will start with this one. No one was really out of line at the table, CO liked to raise it up a lot PF and betting postflop got aggressive at times at the table.
Any advice appreciated, especially what the proper play on the turn would be and why.
