I've also heard that if a man has a penis too large, it is uncomfortable for the woman. Somewhat like men and a female's breast size. A lot of men prefer medium or smaller breasts.
the big cock issue is not true for the majority of women... a decent sized cock..about average.. is just right... too big just gets painful for them... although theres aot of women who enjoy deep stretching of the vagina.. which only a big cock can provide... but most women think its painful ad not pleasureable... most of the sensitive nerves in the vagina are within the fisrt half inch or so... and women are much more orgasm prone from clitoris stimulation than inner vaginal stimulatiopn anyway...which has nothing to do with cock size..
