Red is not a girly color, but in very traditionally macho environments, any dissent from grays / black / blue will certainly bring a little ridicule. Then again, do you really care if it does? You like the color, you should get it.
Personally, I bought an older iPad shuffle in Orange because I like it. I've also owned a Green iPod mini. In fact, if I could get my iPhone in orange, I would have! Guys should not feel girly just because we like to express ourselves with color. Remember-- nothing is inherently girly or masculine. It's social norms that establish that. And red is, at worst, a-sexual-- meaning it is not strongly affiliated with either sex in our culture.
Here's the best way to look at this from a designers perspective: red will garner attention and show you have confidence in your choices. You don't even need to defend your choice. You simply assert it's awesome. You might be surprised how well that works.
