Pokerstars 1/2 QQ

[Badger]

Villain appears to be somewhat aggressive and a little loose.

How do you feel about the slow play here?
Reasons I did it-
My thoughts are 17 cards in the deck are scare cards for me. And I think the ones that aren't make for a better raise on the turn.
If villain has a FD:
If he's going to bet it at me I'd rather wait til the turn is clear to raise him.
He could have a made straight, but I'm not really worried about that yet.
If he does have a Q or smaller PP I want him to think I whiffed so he'll bet at me on the turn again and I can raise him there for .5BB more.
Maybe one of my non scare cards would even give him a set, 2pr or something else.

Is this a good spot to wait?
