I have a similar size (though I haven't measured girth) and I have never had girls say anything but good things about it. A good number have said I was the biggest they had ever been with -- so I think you are in good company, dude.
Average is supposed to be what? 5.5?
1.5-2 inches over average is like a 20-35% difference -- that's a lot!
Don't feel discouraged by the abundance of 10 inch schlongs you see on this website...those are the exception and not the rule
