Chances are you'd not kick her out of bed or not date her if the rest of the package is nice, but truth is, you'll always secretly wish she were at least a B cup.
Penii are the same 5 inches is A cup, 6 inches is B cup, 7 inches is C cup. Less than 5 inches is like.. barely visible boobs
I mean, there's a difference in that you know how large someone's breasts are before getting them in bed most of the time.
Confidence is the thing. Girls will flock to a dude with confidence and the dudes with confidence usually have an above average shlong. So in a way, women know how to "size" a guy up before getting him into bed.
This the truth. I've had girls tell me they could tell I was packing just because of the way I carried myself ---
