I'm sure this depends on lots of other circumstances beyond type (what doesn't :), but would you say that what you're looking for in a potential mate is the same for short term vs long term (or casual vs serious, if you prefer)?
Do you think NTs are more inclined to only seek out potential mates that have long term/serious potential, ie not be interested in short term/casual relationships?
If someone doesn't quite match what you're looking for in a long term "potential mate", do they become...a short term option? A friend? An acquaintance? Forgotten?
