DaasYochid: Thank you for pointing me to the Rashbo. I read (and re-read) it carefully and also looked at the gemoro in Nazir to whioc he alludes. In truth, the teshuvo raises more questions than it gives answers . Firstly- the person asks the Rashbo the question whether the custom of people “shaving under their chin and the throat” (obviously to avoid “hashchoso beta-ar in “Pe-as zekeinecho”) is allowed, as the people do it all the time. So, does the Rashbo prohibit this? In other words, according to the Rashbo, can we -today!- shave anywhere? According to your intimation that the Rashbo holds that,once it is a “malbush isha” it remains Ossur forever- dos that mean that we- today- do not hold like the Rahsbo??
Secondly-if you look at the actual gemoro- it ends up allowing to scrape hair from under the armpits ,asl ong as it is with a “beged’ a cloth. Why should that be so, if any shaving like women is ossur?
Lastly, although the Rashbo does indees intimate that any shaving would be ossur- from the gemoro “Nazir” (59a) it seesm that only “chaveirim” followed that precept. Maybe it is only a middus cahssidus, and nto the halacha? More questions tob elucidate this.
