I'm a guy knitter.
In public so far I've knitted on a plane (and the airport), while waiting for my brake pads to be replaced, and in a few bookstores.
I've been knitting now for just over a year. I learned at work through my boss. We were having a discussion that somehow went to knitting. I mentioned that I had always been interested and she said that she knew how. The next day she came in with a new pair of needles and a ball of yarn for me and taught me how to knit, purl, cast on and bind off.
I attempted to knit a few scarves. My first project was really experimental. I was just practicing stitches and creating small chunks of garter and stockinette. The next scarf I attempted was fast but too short to be used(I had only purchased one ball of the yarn). My third scarf was ribbed, after about a foot I made a mistake. I didn't learn how to fix a mistake, or rip back a few rows and re-insert my needle so I quit.
About nine months later in October I took a random trip to Michael's, bought yarn, and started knitting again. I'm finally able to repair any mistakes now thanks to knittinghelp.com and I can't stop knitting or buying yarn.
