I see I was unclear.
First of all, every girlfriend I've ever had has either already been interested in gaming when I met her, or gotten into gaming through me. I wouldn't dream of hiding it, and it's typically an activity we end up doing together. (I've actually gamed with most of them, though in one case only after we broke up. One only got as far as making a character before we split, and another turned out to dislike my preferred style, and vice versa, so she didn't stay in my game for long.)
Second, the above incident did not happen when I was eleven, it happened last year. "The only time X has happened *SINCE* I was eleven" does not mean "I was eleven when X happened" - if anything, it implies that I wasn't.
Third, as I believe I said, I was only embarassed because the guy went on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on about his old, munchkin characters even though both the people he was talking to were trying to make it clear that we would like him please to stop - and I was guilty by association, or that was how I was made to feel anyway, because he did so in response to a comment from me. Before that, we had her interested and asking questions.
I don't know where people got the idea I was one of the people who hide their gaming. No offence or anything, but did you people even read the last paragraph of my post?
Edit - corrected one typo.
