In a situation when a man will both be lighting the Yom Tov candles and making Kiddush, when should he make Shehecheyanu?
Do we say only when lighting candles, since that is when the women say it when they light candles (and perhaps because that is the earliest possible opportunity)?
Do we say that they should only say it when making Kiddush, since that is when it would normally be said?
Or, are there certain times when men would say the blessing both times, such as when the Shehecheyanu in Kiddush also applies to another Mitzvah of the day. For example, would the man say Shehechyanu both when lighting the candles on the second day of Rosh Hashana, and during Kiddush when we are supposed to have in mind a new fruit or garment when saying the Shehecheyanu (Orach Chaim 600:2)?
And, assuming the man is supposed to say it twice, what does he do if already said it when he lit the candles and he doesn't have a new fruit or garment? (Normally Shulchan Aruch says to say it anyway, but in this case he has already said it when he lit the candles)
Take Sukkot as an example. The Shulchan Aruch (Orach Chaim 641:1) tells us that the Shehecheyanu we say on the first night of Sukkot is also being said for the Sukkah. If for some reason you said Shehecheyanu on the first night of Sukkot outside the Sukkah you repeat it the first time you sit in the Sukkah. If so, it would stand to reason that if the man said it when he lit candles he would still repeat it when making Kiddush in the Sukkah. In such a situation, should the man skip it when he lights candles and only say it in Kiddush, or should he say it twice?
