If you have someone who can help you take measurements, why don't you see what the various calculators say about your fit? Competitive Cyclist has one which gives 3 different sets of suggestions, and you can find a bunch more calculators by searching the web.
An 11" drop from inseam to seat tube length (C-T, I'm assuming) seems excessive to me, except perhaps for racing, but my thinking maybe outdated.
Also, if your inseam is 32" and you're 6' tall, it sounds like your torso is relatively long. That means ideally you need a longer top tube than most people your height, and production bikes are presumably made for average people. (That may not be true.) That's just more logic in support of the proposition that your bike is too small for you.
