No different than any other group of people, some would be more open (or tolerant, maybe) to that sort of thing than others. I lean heavily toward not asking without a relationship for reasons other than learning about such things. A longer (or more personal, maybe?) relationship than buying something at a shop, for example. And then, not too many questions without a lot of welcoming responses from the person. I know I don't much like questions about things about me that are different than the norm without the relationship.
