To be a little fair to the elders involved, they were more likely trying to determine if what you told them constituted "fornication" or "uncleanness" or "loose conduct" (now "brazenness"). The words have "overlapping" meaning (no pun intended). They have to do this so as to satisfy the legal (elder's) manual. It is somewhat an exercise in WT legalities.
Usually at KS schools (and I think in the elder's book also) they are counseled to avoid asking detailed questions beyond what is necessary so as to determine the type of sin involved. But the definitions involved and the need impressed upon them to be correct in (WT imposed) detail and the fact that the CO will be reviewing the case within the next 6 months, all these things put pressure upon them in such a way that they often times go beyond what is seemly.
If such things were not held in such secrecy, then human decency would probably prevail more often.
