A discursive dilemma is when two different choices look like the right choice, but they both have drawbacks. For example, if you have to decide between two different activities, like going to a movie with your friends or staying home and doing your homework, both choices could be right but they also have drawbacks. Going to the movie with your friends is fun, but you might get behind on your homework. And staying at home to do your homework might mean you miss out on a fun activity. This is a discursive dilemma because it's not obvious which is the best choice.
