99 too passive? too weak?

[HouseCalls]

First rotation but seems to be relatively tight game for this level - about 3-4 players per flop. Other than that no reads yet.

Preflop: Hero is UTG with 9[img]/images/graemlins/club.gif[/img], 9[img]/images/graemlins/heart.gif[/img].
Hero calls, <font color="#CC3333">MP1 raises</font>, <font color="#666666">1 fold</font>, CO calls, <font color="#666666">2 folds</font>, <font color="#CC3333">BB 3-bets</font>, Hero?

I was pretty much following SSH tight game prefop guide here and just called with the 9's - is this too passive here?

I routinely call 1 bet back to me preflop but treat 2 bets back similar to cold calling and almost never call here. Is that to tight???
