Good time for turn sexy?

It's fine but only if you're check raising the turn. The call turn bet river line makes no sense. If he has any pair he'll probably bet the turn and may well call a raise and a river bet (but probably won't bet the river if you call his turn bet). If he has a flush draw then he may well bet the turn and call a raise as well, but won't put in any bets on the river if he misses. So IF you're going to check the turn you need to raise.

Note that this is another example of how being out of position means that you need to take a more conservative, ABC line.
