What most women are too polite to say out loud.
This applies to the vast majority of under-endowed guys (like me) who have lost one girlfriend after another because of this "little" problem. There are some males that are better off locked in a chastity cage and dominated by a girlfriend, wife, or mistress.
Her accent is a bit difficult to follow at times, but you'll get the point.
I don't think this is true for me at least. I've had perfectly fulfilling sex with a 3-4 inch guy. A big guy is very animalistic and a smaller guy is more intimate and erotic.
Cock size is just what it is. I'm a beta at home who has a large erection but a tiny flaccid cock - I call myself a super-shrinker. But this means I need a small cage, and the best leveller of all is not being more than two inches for weeks at a time. I'm definitely better off locked.
