Seriously, a search in the app store for “sex apps” will provide you with pages and pages of results of various sex topic apps. A few are free, but many are only .99, so that you don’t have to break the bank to have some fun with these sex apps.
Now open the Settings app and choose General Restrictions.
Tap the Websites button under the Allowed Content group.
Rather than blocking a website or two, you can take things a stage further and only allow access to a set list of websites.
This is obviously safer than blocking sites, since you know that your child won’t be able to stray onto a new unsavoury website that isn’t in your block list.
So only do this when you really do want to remove Restrictions on a semi-permanent basis.
