Privilege (like male or white or whatever) is not one example of a difference or advantage. It is the culmination of all of the differences that tip the scales generally in favor of one group over the other. You give one case and call it male privilege. I think most men would be happy to trade your concern about your drink being spiked for the expectation upon them to usually buy your drink. Or more seriously, their concern about being killed in war. There is no male privilege or female privilege. Each group has different advantages in life. To the extent we can, we should try to minimize the disadvantages and maximize an individual’s opportunities. You seem to not grasp what privilege is.
