Looks totally different

When I sext this guy he will send pics and videos over snapchat and his dick looks a lot bigger than it really is. He's not using anyone else's photos, it's his bed sheets and his boxers in the picture so I know it's him. When we have sex or fool around it just looks like 3 inches smaller tbh. over video it looks like almost 7. in person it looks like 5 or 5.5 in. I guess he has mastered the art of illusion lmao
