I think your straight is good here enough to try to make it to showdown. Villain could have adx, a set, or two pair. If he has the flush, you're screwed but you know this.

If he has adx or a set, your reraise is not enough to make him fold. If he has 2 pair, he will probably fold. And so if you are going to reraise, I think you have to reraise a lot more.

Alternatively you can call and make your play on the turn, depending upon what falls.

How I end up playing the hand on the flop would have a lot to do with my opponent's tendencies and ability--though even bad players flop flushes. Also if I felt like he'd flopped a flush, I may give up on the hand. I know it is dangerous to make decisions on a feel read when playing on-line; but at times, rightly or wrongly, I will make a decision on this basis.
