I don't know what you mean by "original text". We certainly don't have an 'original copy' of Genesis 3, but perhaps you simply mean "are issues of nudity and shame caused by translation?"

The text in question involved Genesis 2:25, 3:7-13 in particular.

2:25 וַיִּֽהְי֤וּ שְׁנֵיהֶם֙ עֲרוּמִּ֔ים הָֽאָדָ֖ם וְאִשְׁתּ֑וֹ וְלֹ֖א יִתְבֹּשָֽׁשׁוּ׃

And the two of them were naked, Adam and his wife, and they were not ashamed.

3:7 וַתִּפָּקַ֙חְנָה֙ עֵינֵ֣י שְׁנֵיהֶ֔ם וַיֵּ֣דְע֔וּ כִּ֥י עֵֽירֻמִּ֖ם הֵ֑ם וַֽיִּתְפְּרוּ֙ עֲלֵ֣ה תְאֵנָ֔ה וַיַּעֲשׂ֥וּ לָהֶ֖ם חֲגֹרֹֽת

And the eyes of both of them were opened, and they knew that they were naked, and they sewed fig leaves for themselves as a covering.

There's little doubt in the Hebrew text, associating nudity and lack of shame with a pre-fall existence, whereas 3:7 occurs after Adam and Eve eat from the Tree of the Knowledge of Good and Evil.

That is, awareness and attendant shame regarding nudity is regarded as a consequence of sin, not an inherent feature of nudity.

That's part one of my answer. If I get a chance I'll come back and write some more about early Christian attitudes to nudity and shame.
