I’m only barely over 5 inches. I know I’m Bi, although slightly embarrassed by it, and have always been the dominant one when it comes to sleeping with woman or people with a dick size equal to/smaller than mine. I’m just curious as to why I can’t be dominant in bed when someone’s dick is even slightly larger than mine. It makes my knees wobbly and my heart throb while my mind goes complete blank. Why do I feel this way? What makes someone with a bigger dick size stand out in my mind so much?
