Hello numbnutter,
Well, even if you Call it preflop I don't really see why we should raise on every damn street.

From what worse do you get called?

He could easily even be trapping. I would rather at some point just take pot control and be happy if I even win the pot. You have only 40 hands on him and no notes/or table dynamics written here.
Flop raising is fine but afterwards I'd just Call and reevaluate further actions.
Best Regards.
