Stage of the relationship: Casual sex

If you're her boyfriend, feel free to request breakfast and sex at the same damn time. If you're someone she's having casual sex with (or worse, a one night stand), don't assume that just because you were lucky enough to bed her the night before, she'll automatically grant you another go-round in the morning. If you were the best she ever had, she might oblige you, but that's a bonus round, not a requirement.
