Do it! Do it NOW!!!
I started knitting two months ago, and I'm presently within a couple of hours of completing my first pair of hose. (It helps that I'm sort of an over-achiever when it comes to learning new hobbies.)
Upsides: the gals at my favorite knitting shop adore me. I'm a guy, I learned only two months ago and I'm already knitting hose, I'm sociable, I wear a kilt, I hang out with a shopful of knittin' women on knit nights and I go right along with all their conversations (which can be a bit weird at times, but certainly educational!), and my wife loves that they're all jealous of her because she had the luck and skill to marry a real gem! 
It's e-a-s-y to learn to knit. All decent yarn shops offer classes - as does Michael's, in case you have one nearby. You'll start with a scarf, which quickly becomes frustrating, then rewarding, then boring, then rewarding. Then you'll increase the complexity by knitting a scarf with a cable or rib pattern. Then you should do a hat with ribs and cables 'cause you'll learn decreases or increases and knitting in-the-round, and you can challenge yourself to learn more on every project. What's gonna happen if you mess up? Ha! Nothing!! You just try again!
Books are good. But learning from an experienced knitter who's excited to teach a man [in a kilt] how to knit is THE way to go.
I knit everywhere I can get away with it. My wife and I go to bars and knit. The guys give me funny looks like they think I'm a poofter, but then their girlfriends/wives say "Oh! Look! A guy knitting! My grandmother taught me to knit when I was a girl... (sigh) I should go back to knitting again..." And then the guy who gave me a funny look is jealous that his gal finds me attractive, and he no longer thinks I'm a goof for knitting. Trust me - it's true!!
Alright, I'll stop now. I think I've successfully communciated my enthusiasm for knitting...
