villain in this hand is 18/16, he is quite aggressive, likes to make moves but nothing too spewy. He feels that I'm 3 betting his LP raises too much so he is not giving too much respect to my raises.

Flop: [3s][7h] ($167, 2 players)
Hero bets $120, CO calls $120
Well my flop bets don't mean much since I'll have pair or better here like 30% of time. So if he caught some part of the board he will try to float.

Any suggestions on PF? I cant just call here, and I cant 3bet more $$ since If i 3bet now to 100$ or so.. I will have to do it every time to a steal and that wont be profitable.
