5/10 bottom set on flush board turn minraise then push

[SmackinYaUp]

Ok, so I'm new to 5/10 and play on the conservative side. I have been raising and reraising pretty light preflop but postflop I've basically been super tag. Thing is I only have 21 hands against the guy so I don't think my image mattered much. Before this hand I haven't even been in a pot against him. I just call the turn minraise and am lost on the river. I might have called, might have pussed out...How should I have played this hand? I had a really hard time putting him on any specific hand. He's been 38/15 over those 21 hands for what thats worth
