I finally had sex with this very sexual Indian woman I work with. She is really into kama sutra and tantric sex. When I took out my package she examined it thoroughly - length and thickness. She didnt say anything. I finally entered her after stimulating foreplay. I thought the sex was good but she did not seem to be into it as much. After we finished she said that we have a "low union" meaning that my penis does not fill up her vagina adequately. She explained how women prefer "equal or high unions" for the ultimate sex - meaning the penis must be the same size as the vagina or bigger. Is anyone familiar with this concept?
