Django - create a foreign key with boolean

I have some questions on my site and I want them to be seen only by users that I want. I created a profile class and for each profile I want to create a boolean Field for each question. For the moment my code looks like this :

class Profile(models.Model):
   user = models.OneToOneField(User, on_delete=models.CASCADE)
   accessquestion1 = models.BooleanField(default=True)
   accessquestion2 = models.BooleanField(default=True)
   accessquestion3 = models.BooleanField(default=True)

Can I optimize this code with a kind of 'boolean foreign key' ??
