I think more highly of skinny/out of shape guys at the gym than those who complain but do nothing. The guys at the gym at least get some credit for effort. As has already been said, you have to start somewhere. Sure, a lot of people find the gym intimidating and think they need a gym body before they can step one foot in the gym. But, that's just not rational.
My biggest suggestion is that you should not be afraid of asking for help. If you don't know how to use a piece of equipment, you shouldn't be using it. Ideally, you should have a trainer your first 2-3 sessions so you can learn what you're doing. Yes, after investing in a gym membership paying even more for a trainer is painful, but if you're doing an exercise incorrectly at best you'll not slow any progress or at worst you'll injure yourself. Believe me, I had the benefit of a trainer, and it made a big difference. And now I try to stop newbies when I see them doing something really wrong.
If we're talking about you specifically, I think you look fine. I'd suspect you were just really lean.
