Not at all. While there's the obvious "it's not even gay" part, even if it were gay, it wouldn't make it less "manly". Homosexuality is a fairly modern concept in the Western world, created only by religious stigma. In ancient Rome, it was very unusual for a man to exclusively prefer women. In feudal Japan, it was actually considered more noble to be homosexual.
So no, I don't feel any less manly.
