Instagram is now allowing users to have more control over what they see in Explore. The new control will provide new options to see more or less sensitive content. 

To view your Sensitive Content Control, go to your profile, tap the Settings menu in the upper right corner, tap Account, then tap Sensitive Content Control. Here you can decide whether to keep the setting at its default state (“Limit”) or to see more (“Allow”) or less of some types of sensitive content (“Limit Even More”). You can change your selection at any time. One exception to this: the “Allow” option will not be available to people under 18.
