It's not hard to find real men in country music. Most of the guy singers qualify. There are a few exceptions, though. I don't have anything against Keith Urban, for example, but the guy paints his toenails. That sort of thing just doesn't cut it for real men.
However, there's one guy that we should take the time to recognize. And that guy is Trace Adkins.
He sings about hot chicks, hard work, the military, and vehicles. He can also sing tender songs about love and family without anybody questioning his manhood (because let's face it, he'd kick the crap out of them). If the hit songs and Opry membership weren't enough, he's also had his nose nearly detached in a car accident, his fingers severed and reattached, survived a hurricane on an off-shore oil rig, and been shot through the heart and lungs by his ex-wife. And he's lived to tell/sing about it all.
If that doesn't say "real man," I don't know what does.
P.S. I also highly recommend his book, A Personal Stand: Observations and Opinions from a Freethinking Roughneck.
