Leading the flop is fine if you're willing to play this hand for stacks and if you sometimes smooth call AA KK preflop and he's seen you do it.
Otherwise, it's obvious you either have an overpair smaller than JJ or a flush draw (assuming your preflop rr range is tight). Since there is a limper in this hand, it is very very likely that this is a position raise which increases villain's range. I've done this with anything from 56 unsuited, KT suited, Ax-suited, depending on my mood. But, with 2 callers, I'm only betting that flop with any pair or a flush/gut/straight draw. A turn check is therefore suicidal for you, since if I had a flush/straight draw, I may check that turn fearing the check raise. Then if a scare card hits, you're forced to make a pot sized tough call on the river, or worse, a raise.

As played, you HAVE to lead the turn...but your best option is a check check or check fold.
