ThickMeatJacker, there is no connection; no direct correlation with height and size.
Check out the porn star, Shorty Mack (sp)...., a short man but a girthy cock. The majority of women can't take him: some can take about 1/3 or 1/4 of him, with the exception of Zoe Vass, my heroine.
She took all of him, cumed on his cock, and wanted more of him: so, he accommodated her tight vagina. She is a slim, petite woman, but I was surprised she could take him.
Now, some women who self-lubricate are fortunate enough to endure fat, girthy cocks like Shorty. However, some women must use lubrication, which is fine.
Anyway, you are blessed, be careful, and enjoy your fuckings. One day -- it will be over.
Denise.
