I'm one of them. I dated a guy the summer before I got my first snake, and he knew I was obsessed with snakes at the time. He even bought me a snake book. Unfortunately, we were never meant to have as clutch together and I have no idea where he's at now.
The point from my POV? Your girlfriend doesn't have to like reptiles as long as she likes YOUR snake.
OK, that was terrible, don't blame me, blame the beer. 'Cause I've been drinking it.
