Could Italian castrato singers really have sex?

by StraboSE

This might come off a bit strangely, but I was reading a history of music and came across the subject of castratos in the eighteenth and nineteenth century. Beyond the cruelty of human castration I found the description of some of these men being sought out as sexual partners or even actively seducing women rather shocking. As someone from a rural background I would not expect a male who. has undergone such a procedure to be capable of intercourse, much less to be so renowned for their skill at it to allegedly have women declaring "blessed be the knife" in the audience, as the book claimed. Is this actually the case?

More of course can be said but this old AMA includes some stuff from /u/caffarelli touching on this topic so should be of interest.
