I don't really worry about size, since there's nothing you can really do. Sure there are operations and such, but that's risky, and weight's or whatever sick crap there is out there is nasty.
Is that something to brag about? That you wouldn't be able to tell your a girl. Seems like it hurts you, but I'm an idiot.
A lot of women believe you have to "inspect the package" before you marry someone. To see if you got a "dud" or a "stud".
