Oh my, this is hard hard hard because I happen to consider every male I like in books my personal book boyfriend and you might guess by now I have a splendid harem.
My attempt to do a top 3 got me 15 names so since I've been doing a good work so far in picking only one choice for each day I'll do it again.
And the oscar goes to
Reginald Jeeves!
from P.G. Wodehouse's series of short stories, novels and tv series.
I had read Thank You, Jeeves and several short stories before I'd known about the Fry & Laurie tv show of it and then I came to love it even more because they're so perfect at it.
