I agree with slickslack.

I'd have pushed all-in on the flop and hoped that someone else had something like a set or a small flush OR that they thought I was trying to steal it. However if you are coming across as tight/passive then you are not likely to get a call. If you play a little more losely and show that you are game to go all-in on occasion, you'll increase your chance of getting action.

I wouldn't play A small suited because when you hit your flush, as in this case, you probably won't win very much as the others are likely to fold when you bet. And if you don't hit you can cost yourself a lot of money if you chase. And what would you do if faced with a pre-flop raise? You don't play draws against just one or two opponents.
