If you were looking for a guy with those requirements, then it'd be pretty easy, but girls like that are fewer and farther between. They do exist though, and are typically looking for guys who share in their interests, so just keep going to expos and stuff and you may meet one. You're more likely to find a girl that is tolerant of snakes, than into them though, or an animal lover who is more into fuzzy things but has nothing against snakes.
My husband isn't into herps at all, he's kind of afraid of them...not like they might bite, but he says he's scared to hurt them (maybe that's just an excuse lol). He did hold my BP last night for the first time though (I got her a month ago), so maybe he's coming around.
I could see this being a problem if you ever decide to get any very large breed snakes that might pose a perceived risk to children. I don't know how old you are, but if you become serious with someone (even if she is into snakes) and she starts thinking along the lines of starting a family, you very well may get an ultimatum.Yea I don't mind converting but my ex when I first got into the snake hobby said to choose them or her, needless to say I have my snakes still to this day.
