The first guy I ever had sex with was the thickest about 3" in diametre as a virgin it couldn't fit all the way in. It was also about 9"or more long. The third guy was the only other large dick I have had, he was Polish and over 2 metres tall and had a cock to match. It was longer than the length (the long edge) of an A4 sheet of paper. It was truly heaven. The rest have all been unexceptional, but still OK. But every time I have sex with my husband who is only average at 7.25 I still wish it was bigger, like my polish lover. Now 20 years later I still think of him and wished he'd contacted me again. YES, YES, size does really matter.
