Well, my experience isn't hiding gaming from girlfriends, I've been married since I was nineteen and my wife knew I was a gamer the day we started dating at 16. In spite of that knowledge we’ve been married for 16 years and I couldn’t be more in love. But goodness do have a lot of funny stories to tell about her and gamers. You see I'm a rather lucky fellow in that Katy is gorgeous... by anyone's standard. She gets flirted with all the time, has been asked out more times than I can even begin to count, and even by men who already knows she's married (which just pisses her off to no end). I’m not Mr, Attractive so I guess these guys think that she is available because we don’t seem to match when you look at us casually.
I've run a lot of games over the years, and nearly always at my house as I have always had a game room of one kind or another. I've run the same group of fellows for just over eight years so they are all quite used to Katy being around now. She is very friendly and has a talent for making people feel comfortable, unfortunately some guys think this means that she has taken a shine to them, when in fact its just her lovely nature.
One fellah, a friend of a friend who was allowed to game with us once, when introduced to her turned red in the face and just stood there for an odd moment or two. Then he blurted out "Hi Pookie"! Katy looked at him like he was insane (which he might temporarily have been) and he wasn't invited back after that.
Another fellow kept telling me for days what excellent massages he gave after Katy was overheard by the group telling me that what she needed was a deep shoulder rub.
Another guy who I thought was a friend went so far as to proposition both of us for a threesome after a game meeting... he was disposed of immediately (the police never have found the body).
But many of the gamers that have come and gone over the years just become deathly quiet when she comes into the room to say hi to me or sits on my lap. It's like a friendly pretty girl is death to role playing. One guy had it so bad that he turned red as an apple every time Katy entered the room. I felt so bad that I asked her to not sit on my lap when he was about (she and I have always been physically affectionate but try not to embarrass other folk).
I'm very happy to say that all my current gamers are very comfortable around her and many of them even go camping with us with their own families at SCA events now. But the things I mentioned here are just the tip of the iceberg of the things that have happened over the years... oh boy!
