I don't have a sister or a daughter. But if I did. . .
It wouldn't affect our relationship in any way. However, being hung like a chipmunk myself, I know I'd be secretly curious about how their sex was. Was he cutting the mustard with his small dick? If they broke up, I know it's stupid but I'd attribute that to the size of his cock. A friend of mine's sister married a Japanese fellow. Have to admit, when they divorced, that thought definitely crossed my mind.
Of course, there might be those who've had thoughts along those lines when I broke up with my first wife. Or wondering how my current wife and I are doing in bed.
