It's difficult to answer. We're people too. We do all of those things. I'd like to say that we do it less than other groups, but I doubt it.
Of course, I can only base my answers on the ones I actually know.
We don't usually engage in premarital, but it happens. My mother was Christian when she got pregnant with me at 14. I did it once before I converted about three years ago. We aren't supposed to do it.
I don't listen to Christian heavy metal, nor do I know any Christians who do. The whole genre seems silly to me. It's great that they make it, I guess, but you won't catch it on my hard drive.
Yeah, quite a bit. I struggle with it, and I'm sure some of the others do. I never asked though. It's embarrassing.
Yes. I don't believe God ever said anything against violence entirely. Murder and such, yes, but not violence itself like He did lying or taking his name in vain.
I do. I shouldn't, but I do. I try not to, but after a while in the military, it's hard to not drop an f bomb whenever someone screws up or almost gets me killed by general idiocy.
All the time. Like I said, we're human. I have the benefit of being married, so I can, within limits. I can't lust after other women, but my own wife is fair game.
Yes, but again, we probably shouldn't.
They aren't all right or wrong. Sometimes it depends on context, a good example of which being me and my wife thinking about sex with each other.
