My wife can try any cock she wants. She has told me it is impossible to know if a guy has a big cock or not until its out of his pants and subject to inspection. She goes for the face and personality - big cock is a bonus. The one major problem when age or race is involved is the statistical probability of disease. We all know that alcohol and hormones can lead to bad results. When she has enough wine in her to allow a guy to play with her, and she is fondling his cock, she knows that the lust to suck and fuck can easily overcome good judgment. She is compelled to suck cock bare boner. She is lust driven and loses any ability to demand condoms or sex history - just wants it now. So she avoids young black guys because they have a high probability of STDS. Older black guys also loose out because if Hep C. I guess that is why mature white males are in demand by black females.
