u flop a trips, opponent min bets. what now

If you have an agressive style you are getting calls from a lot of medium and big pairs if you bet here.
If they fold a lot you should bluff more at this kind of board.

You can't force your opponents to have a hand when you flop trips, but you shouldn't get less agressive, because in that case you don't win a big pot when they have nothing AND you don't win a big pot when they have something. While if you always bet here you are winning a small pot when they have nothing and a big pot when they decide to play with an overpair.
If your opponents will give you enough action when they catch up AND you have reason to believe noone has a made hand here AND there are no or very few possible draws, then you can decide to let them catch up a bit and check it.
