Blood cock or flesh cock

A young lady that I had just started dating was grasping my cock through my pants for the first time. She asked, are you a blood cock or a flesh cock? I did not know what to say. She explained that a flesh cock is normally larger when flaccid and does not grow much when excited (filled with blood) but a blood cock is usually much smaller when soft 3-4 inch range but grows much more when it fills with blood and becomes very hard. I am a blood cock and my cock is about 4 inches when soft but doubles in size and thickens greatly when fully charged. She said she liked that because it was nice to take a small cock between her lips and suckle it and then feel it grow much bigger.
