Girls, Question for the ladies... I have an 11 inch penis is there a thing as to big?

I took a girl out to dinner the other night we had a few glasses of wine brought her back to my place put some music on and started kissing. I was feeling her up rubbing her down there where she was moaning and started jerking me off over my pants so i took them off & my boxers came off too... She stopped and grabbed my penis with 2 hands and she just stared at it got her things got dressed and ran out. I tried calling her but no response... What did I do wrong? was I too big?
