It is very exciting. The male protagonists in all your novels are heroic in some sense, and yet often flawed. I find perfect men boring. A perfect character is like a beautiful, placid lake. You can admire it, but eventually you look away and try to find a little action.
Flaws are human and it gives a character something against which to struggle.
However, it can be hard to balance. In one book I reached almost the halfway mark and realized my male protagonist was too noble. I was in a terrible dilemma because the plot wouldn't permit a changed in character. I do not find creating male characters any more difficult than creating female characters. I like dealing with male protagonists.
