top pair on flop, bet into on turn -- what to do?

[rgb]

SB seemed run of the mill player... fairly loose but nothing noticeable otherwise.

In this situation quite often and I don't know how to proceed.. flop top pair but get bet into on the turn.

Here, I think I'm probably behind but folding at the first sign of aggression seems weak. OTOH it's a small pot and a coordinated board so maybe best just to drop?
