What are you scared of? 34? 56? Villains have something like 77-JJ. Youre miles ahead, reraise here. While its possible they have 55, 66, or 22, those hands dont generally try and push out the initial raiser -- they use the initial raiser to build the pot. I think youre good here, and I like a reraise. Every turn card for you will suck, get your money in here on the flop.
