Is this too aggressive with small pair?

[KHALI]

Ok to set the stage I have just started playing poker this year and just moved up to the $25NL tables so I am inexperienced. I had shown down two big hands in the past half hour(KK,QQ)so I hadn't played any garbage and got caught yet.The villian had raised almost every single hand and showed down some suspect holdings like a baby ace, Q 9 suited etc... so I figured he was full of it. Regardless of my read here is my play correct or a bit crazy? I think I made a mistake by not reraising enough(make it $10 maybe or push I guess) and my other mistake is giving him more credit than he deserved for being able to fold a hand. I am posting here because I remember a discussion about folding equity. Is this an example of no folding equity? Anyway comment on the play and what you think.
