continued discussion of #3163: The Science of the Test Described in Ketubbot 10b

I here the answer/teshuvot but there are difficulties:

1. Vaginal muscle tone varies dramatically due to genetic variation. This is a medical fact that can be confirmed with gynacologists. It is also has been a problem even in certain relationships (even causing divorce) where partners couldnt easily do penetration due to overly tight viginal muscle tone that doesnt change after penetration (or even overly loose where women or man get lower satisfaction)

2. The thesis may be correct for prostitutes,very frequent sex (and DEFINATELLY BIRTH !)but vaginal muscle tone isnt likely to change all that much post a few intecourse events. In halacha only ONE is needed for the designated label of "non virgin".

3. Variations in muscle tone can actually be artificially changed for example doing Kegel excercises Kegel exercises restore muscle tone and strength to the pubococcygeus muscles. Kegel exercises are said to be good for treating vaginal prolapse and preventing uterine prolapse in women (and increase sexual pleasure).

However there is also natural variation in pubococcygeus muscles. Point one and two in the teshuva about the similarity of alcohol to garlic in absorption I simply dont know – it is unethical to test this today (statistically corrolated double blind controlled trials didnt exist then) – but lets say the "experiment" did work (the theory is OK and "Emunah chachamim" we assume Rabbi Gamliels test worked – except its not statistically valid) it still poses a problem of the massive genetic variation where innocents will become guilty. Women with naturally large surface area exposure will become designated as non virgin and those of small surface area designated as virgins. Is there any additional information or opinions that has been researched ? Thank you very much and shavuah Tov
