skripka, while I am making a light-heared argument here, I can tell you that – in my humble experience – if the lady in question smells wine, she is drunk. And, if she is sitting on a barrel of free wine and controlled herself so much that she did not drink any – she is a tzadekes. And this ability to withstand the yetzer very much correlates with the condition of her reproductive system.
Come to think of it, maybe that _is_ the allegory the gemorah is making – barrel of wine as yetzer.
