I don't think they're males. If anything, wait a bit longer; if you see blatent sacs then I'd start worrying. And you might want to lower your N for flowering!

I've only had experience growing AK47, Sharksbreath, Bubba Kush, Privada Cole Train & Church, but I'd have to say Church is the best hands down - great smoke and attracts a lot of cats. Ha.
