5/10, double gutshot and flush draw on flop, jam or wait?

[Jonny]

I usually play 10/20 but decided to play some 5/10 as I have been taking a beating. No real read on the villian, I think this is the first orbit.

I could have re-raised the flop, but I feel the stack sizes were awkward, and I was OOP. Pushing on the flop I feel I would only get called by a hand that is crushing me (set), and nothing else. So, how do you play this one?
