hello, Rav Moshe is talking about a romantic phone call in the context of a teshuva about dating.
Zahava, the term is “eshet yaffet toar” (beautiful woman).
Health, this is not gilui arayot. According to some opinions it is even muttar lechatchila as I have posted several times. Therefore, it is totally appropriate for a rav to be meikal if he feels that the situation warrants. In nay case, as I have posted, the fault for the fact that Israel is not yet a completely (there are also many good points – as Rav Kook said light and darkness are blended together) tora state lies squarely on the shoulders of those frum Jews who come here but do not become citizens and vote as wel as those who choose not to come because of their love of Galut (= chet hameraglim).
