Been looking for girlfriend, expectations too high?

I don't think it's necessarily unrealistic to look for someone who hasn't had sex before. They are around...somewhere. However, you would also be likely be talking about someone who is either very conservative or having trouble maintaining relationships for one reason or another. And of course, the older the person, the less likely they'll be a virgin. And for one thing, you'd probably decide whether you like the person or not before you can even know if they've had sex (or you could make assumptions...)
