I met this girl through one of those rating sites recently. She was looking for someone that wasn't so controlling and spent more time with her than on the 'net. Her tongue was pretty cool. It's alright by me.
Funny thread. I bet most the guys here would shite their pants it their girlfriend did this, but most probably would be happy just to have a girlfriend. In any case, yeah its kind suspect, but for the most part, unless she's given you reason to doubt her fidelity, she's just messing around.
