With the foreknowledge that my perspective could differ from you guys', I'd say:
The historical rootedness of everything. The physicality of the worship. The sense of strength in spiritual combat (particularly if one is monastically inclined, which as you might guess Egyptian Christians very much are), in facing forces head on that are much greater than you as an individual, equipped with the holy cross and the prayers of all the saints and the entire Church since the beginning. The examples of saints like St. Moses the Ethiopian, Abu Seifein (St. Philopateer Mercurius), St. George of Lydda, St. Theodore El Shatby (Amir Tadros), and all the Theban Legion -- all saints that wielded great power but used it in a responsible, appropriate way, many being willing to show forth the "weakness that is greater than power" (to quote the Coptic version of the hymn O Monogenes Yios, if I may) in willingly submitting to martyrdom for the sake of our Lord, God, and Savior Jesus Christ. We recognize this as a sign of great power in itself, as they had their hearts and souls fixed on what is really important, instead of giving in to fear: "Fasting and prayers of the martyrs / Gave them the power to stand the pain / Knowing that even losing their lives / Is nothing compared to their heavenly gain." (-- Lenten communion melody)
There is a lot of heroism in it, you know? I tend to think of that as a stereotypically manly pursuit. And to this day we look up to monks and others who are true spiritual warriors. We have never lost that to the emotionalism that characterizes many forms of western Christianity (and has for centuries). I think coming out of Roman Catholicism especially, in my own case...I don't know a nice way to put it, so I'll just say that I just don't want to hear about feelings anymore without the proper understanding that our spiritual lives are not to be guided by them, but by God. And I only found that in Orthodoxy. So I don't know about everyone else, but that's what it did for me. It is the antidote to the shallowness of other traditions, if I can be blunt. I've written before that I didn't leave RCism feeling that I'd been duped (though I could have, I guess), but rather that I had gone as far as I could go, and was spiritually starving. I needed more. Probably a lot of people can relate to that, though that doesn't seem to me to be particularly male-specific. Maybe in the general sense of taking on responsibility/leadership has generally been seen as masculine, but I dunno. My parish was pretty even, just like everyone else has been saying about their own.
