So i have this friend who has a big dick. I think we are the same size when erect 7 inches. But i have never seen him naked with a boner and we have never compared. One time we came close after drinking and we were talking about it and i said id believe it when i saw it. He said he couldn't get a boner when he was this drunk and that i just wanted to see him naked. So i was wondering how i can get him to compare without seeming totally gay?
