Another simple hand...did i eff it up?

[nbake]

Villain's aggression is around 2, but only after 26 hands. Haven't really seen much from him. Pretty loose preflop...Maybe 60.

Do you guys fold this? I think I call down way too often with hands like this. Heads up It seems like lots of people bluff the turn in situations like this.
