I think so, yes.

If he's drawing you want to get it in because duh. If he has a big made hand you want to get it in because some of those hands will shutdown or be frightened at some turns. You may also be frightened. Will you willing play for stacks when the 3h comes? Lots of cards are scary here. Not a shitload, but enough to want to get it in. He could easily have 55 there, and neither of you will wanna play heavy anymore if a scare hits. If he has 99 or something he will most likely not bluff much of his stack at you after you call his raise.
