I'm sure this varies by country and age you're targeting and what you can actually pass for, but generally speaking what's your rule if you're looking for quick hook ups, if you wanna maximize your chances?
I typically go 4-6 years higher than whatever the girl is if I know her age, but if I don't I say 28.
