According to many sexólogos and urólogos: Those men who possess very long-flacid-penis, these long-suffer when they are in condition of erection few centimeters are lengthened very in comparison with what they were measuring when they were in flacid-state. My question is (for each of you who, actually, has a long-flacid-penis): How many centimeters your penis grows when it happens of being in flacid-state to an erect-state?. And I put a hypothetical example: The Mr. John, has a flacid-penis of 18 cm.-long and when his penis is in erection, it measures only 22 cm.-long. John's penis grows ONLY, 4 cm-long between the flacid and erect-state. I would like to know how long his penises grow between being soft to being completely rigid. I suppose that there are men's cases with very long penises (flacid) and on having been in erection, THIS long penis turns into something much longer still, but they must be minimal cases. In a book of Biology of 3er. year of baccalaureate (High Schooll) author: Serafín Masparrote, was saying that all the flacid-penises grow 9 cm.-long between the flacid-state and the erect-state... I think that this one norm is not applied to all the men of long-flacid-penis. Thank you!.
